I disagree, back in 2005 Achievements were a cleaver way to add a bit more challenge, replayability, and also inspired you to explore off the beaten path. It was new and original and was built into the operating system. Trophies followed a few years later as an after though, a crappy "me too" type of add on. Also splitting trophies into Bronze, Silver, Gold and Platinum makes it more of a chore.
Achievements were fun, quick little things, where you could pop open a menu and quickly look at it, and then a totally overall score was there as well.
Trophies were also not supported in all games until way later too and the awful having to sync your trophies everytime was insane. I can't remember if that was changed in the PS4 or not as I haven't even turned mine on in years at this point.
I will say, the Platinum trophy is far better than just saying "I got all the achievements". That is one thing I'll give trophies, but achievements were the original, they were instantaneous and quick and fun and didn't have to sync. Trophies were an afterthought (Even after having an extra year to catch up to the 360) and reeked of a "Oh, our competitors did something cool, let's rip it off"
