I'm not big into RPG's simply because of how long they are. I don't think they would keep my interest for the amount of hours it requires to beat them. I forgot about Persona tho, maybe I'll check it out. (or try out FF on PS Now or something)
Hey, hey, hey! What did we say about keeping an open mind? :)
If you can, check out this review videos of Persona 3. It's what got me interested in the series.
The way the game incorporates the school aspect in the game, without making it boring, but actually fun, along with how you socialize with people, sounded very interesting to me. And I'm glad I gave it a shot because I've been a huge fan since. If you can't play Persona 3 or 4, there's Persona 5 coming out soon for PS4. And it looks amazing.
Anyway, I was Nintendo-only until N64. After that I got a PS2. And I think everyone should try another console at some point, because it really gives you a different perspective. But unlike you, I got more interested in third party games when I got Sony's console, because Sony is just one developer, and there's just so many of quality on the system. The vast majority of my games on PS2 and PS3 have been third party games.
That said, right now there's not much on PS4 that interests me, but starting with Street Fighter 5, there will be a lot coming out for the system this year that I like, so I will get one when SFV comes out.
