Yeah Ambrose is way better on the mic compared to the other two and what's funny is that only recently (according to Ambrose) has he had any freedom on the mic. That Ziggler promo was arguably his best promo in the company so we'll see where this goes.
As for Ambrose's ringwork, it depends on the match. These Suicide Dives and all suck for damn near every wrestler from Ambrose to Big E to Sasha to who knows, I'm just sick of guys doing them. Dudes in this topic are acting like Ambrose is the only one fucking up suicide dives. I can show you a video where Rollins has a horrible one.

What's funny in this case is that Kane is involved. Again.
Ambrose does need to get better at punches and he needs to be more solid with his offense but one thing he does that I haven't seen many wrestlers in this company do these days is he adapts his style. Ambrose against Owens wrestles different than Ambrose against Ziggler (per those tourney matches they had) which looks different than Ambrose vs Kofi (he used more submissions and holds against Kofi). He's constantly changing his style against guys. I can't say that for Reigns, he always wrestles the same, and I can't say that for Rollins, he wrestles the same and he's damn near a babyface with his style. You can comment on how you think his moves are bad but man does that boy adapt when he has to. I mean look at the HHH match and compare that to an Owens match in styles. He changes.
Another thing that Ambrose does against guys that Rollins and Reigns don't do is that he makes them look at great as possible from a booking standpoint. When someone's against Ambrose I always think they're on a new level they haven't reached, they have a chance and can elevate themselves and they usually step it up. When they face Reigns and Rollins I think "well they're gonna put on a great match but be back in the same spot" and that's especially against Reigns. I don't have any hope for them against those guys and that goes double for their current feuds. Ziggler's looking the best he's looked in years against Ambrose, he looks like he can hang a bit. Balor looks like a placeholder until Reigns is back and Rusev went from an awesome dude to someone who's gonna be put down by Reigns to get his name potentially up.
All different dudes who excel in different things. As a whole package though I prefer Ambrose for everything. It's not just about ringwork and what moves he can do. It's about the whole experience. His storylines have also mostly been better I'd say well, his rise rather but that's also another personal point.
