only thing they said is that the genesis version sound better lol
.. What? They said that only the sports games make the Genesis even close to the SNES, that the SNES has far more great games, that the SNES is so much better, etc etc.
I agree with everything they said about SNES vs Genesis. Sonic games could compete with Mario games. Phantasy Star 4 and Shining Force 2 could compete with Breath of Fire 2, Lufia 2, and Super Mario RPG. Streets of Rage could compete with Final Fight, Turtles in Time, and Battletoads with Battlemaniacs. But I don't think anything could could come close to competing with SNES's top tier of Chrono Trigger, Final Fantasy 3, Earthbound, Super Mario Kart, Super Metroid, Zelda: LTTP, Donkey Kong Country 2. Hell I don't think Genesis could even compete with SNES's second tier of Mega Man X, Castlevania 4, Contra 3, Star Fox, and F-Zero.
This kind of "this game is as good as that game" thing isn't always useful because no one's going to remember every good game, and also because systems don't need an answer to every game on another platform to match it. What you need are good games, period. If one platform has more good games in one genre and another platform has more good games in another genre, they can be equally great.
Also, I think that Sega CD and 32X games should absolutely count -- addons are a part of the console, pretty much. I'd count the Satellaview for the SNES as well, of course. My opinion is that the Genesis + Sega CD + 32X and the SNES (+ Satellaview games) are equally great, but SNES only v. Genesis only is probably a narrow win for the SNES.
That said, to try to answer this despite not actually needing equal games in every category (because of being better at other things) --
Chrono Trigger, Final Fantasy 3, Earthbound -- Lunar 2: Eternal Blue (SCD) is, on my list, the best JRPG of the generation. Lunar: The Silver Star (SCD) is also as good as those games.
Super Mario Kart - The Genesis doesn't have a kart racer as good as Mario Kart, but it's great at other kinds of racing games. I don't love Super Mario Kart, I like the SNES version of Street Racer more, but that's still a SNES game. I haven't played the Genesis Street Racer game though, it looks good but was Europe-only.
Super Metroid - Hmm... not sure about this one.
Zelda: LTTP - Landstalker, Crusader of Centy, and Beyond Oasis are all in Zelda: LttP's category, and all are great games. Landstalker is my favorite Genesis game in the genre. Great game! It may not be quite as great as LttP, but it's close; LttP is great, but I don't love LttP as much as some (LA is my favorite 2d Zelda game, not LttP).
Donkey Kong Country 2 - The Sonic games and Genesis Aladdin are as great as the first-party SNES platformers (SMW, DKC trilogy, Kirby). There are only two SNES Mario games versus 5 Genesis Sonic titles (counting Sonic 3D Blast, I do like the game) plus 1 on SCD (and 1 on 32X that isn't as good), so I think it's fair to compare Sonic to more than just Mario.
Mega Man X - They are more run & gun-styled than Mega Man is, but action-platformers are a major strength on the Genesis! Vectorman is a great classic. Vectorman 2 is also great, and Ranger-X as well. The Genesis also has three Turrican games (Turrican, Universal Soldier, and Mega Turrican), while the SNES has two (Super Turricans 1 and 2). The first Turrican isn't great, but the other four are. Super Turrican might be my favorite of all of them, but Universal Soldier and Mega Turrican are fantastic, fantastic games, among the best of their kind (Turrican is such an under-rated series!) Oh, and the three Genesis Shibobi games are also fantastic. My favorite one is Shadow Dancer, but the other two are pretty good as well. And what about something like Alisia Dragoon? There are lots more games in the "good but not great" category.
Castlevania 4 - I don't think that Bloodlines is anywhere near as good as SCIV, but it is a Castlevania game some people love. Maybe mention the Shinobi games here?
Contra 3 - The Adventures of Batman & Robin (Genesis version), Contra Hard Corps, and Gunstar Heroes are all easily better than Contra III. Also see the list above; stuff like Vectorman and the Turrican games are close to this subgenre as well. I love the Rolling Thunder series as well, and 2 and 3 are on Genesis. The SNES has some other good run & guns (Turrican, Rendering Ranger, etc.), but the Genesis clearly wins here.
Star Fox - SoulStar (SCD) and Shadow Squadron (32X) are both better than Star Fox. I know Shadow Squadron isn't a rail shooter, but it is a space flight combat game, so it has a thematic similarity. Or for rail shooters, Space Harrier (32X) is better than Star Fox for SNES as well. The Adventures of Batman & Robin (SCD) is also an amazing racing/rail shooter game. After Star Fox though, maybe the next best rail shooter on SNES is Hyper Zone, and that game is good but not great. I probably like G-LOC about as much as that game.
F-Zero - F-Zero is my favorite racing game of the 4th generation, so it shouldn't be on any "second-tier" list -- it's a far better game than Super Mario Kart as far as I'm concerned. Anyway, my favorite Genesis racer is Outrun 2019, which is also very, very good.
Some things you don't mention -- the Genesis has an overall better shmup library. My favorite shmup of the generation is a SNES game, Gradius III, and the Turbografx/Turbo CD have the best shmup library of the generation, but the Genesis(+CD+32X) do have a better library than the SNES, for sure. Lightening Force doesn't have a match on the SNES, or Silpheed (SCD), for instance. And Nintendo has the least Compile shmups too. Space Megaforce is amazing, but so are MUSHA (Genesis) and Robo Aleste (SCD).
Or how about sidescrolling action-RPGs? Popful Mail (SCD), Wonder Boy in Monster World, Monster World IV... do anything on SNES match those? If there are I don't have them, for sure (Ys III isn't even close, and it's on all platforms anyway).
Or space or flight combat games. Shadow Squadron (32X), Star Wars Arcade (32X), and SoulStar (SCD) are my top 3 in the genre that generation. And the Sega CD version of Wing Commander is better than the SNES version, the 32X version of Star Trek Starfleet Academy Starship Bridge Simulator is better than the SNES version, and ThunderStrike (SCD) is good as well.
And how about polygonal 3d racing games? Virtua Racing Deluxe (32X) absolutely wipes the floor with the not-that-good Stunt Race FX! Dirt Trax FX is better, but it's not as good as V.R..
Etc. etc. I'll stop here.
So sure, the SNES is better in some genres, but the Genesis and its addons are better in others. I can't decide which is better overall, they're equally great.
I feel the same way about sports games and I enjoy playing sports games. I bought NBA 2K9 and played it all the time. I don't see any need to buy an updated version with different characters. I look at NBA 2k15 in the store and I think I already own that game with a different number on it.
I don't particularly care about sports games, but the Genesis and its addons do have pretty good versions of probably my two favorite sports games ever, Hardball III (no, the SNES game of the same title is not the same game, that's an inferior port of Hardball '94 on the Genesis) and NBA Jam TE... I know NBA Jam is on SNES too, but the Genesis versions are better, and the 32X version of TE better yet.
