Some of my favourite games were JRPGs growing up. I always had the impression that while CRPGs gave the player a lot more freedom, I found JRPGs were more about telling one really good curated story.
Games like the early Final Fantasies, Chrono Trigger, and basically anything Squaresoft put out "back in the day" were among my favourite gaming experience.
These days, whether due to my tastes changing, more limited time, or just the genre shifting in a way that doesn't appeal to me, I play very very few JRPGs. A lot have gone the route of the heavily anime-inspired fanservice vehicles that just aren't really what I ever liked about the genre.
I still will play the heck out of a Persona game though.
I like SMTV, but if you are coming from Persona it is a VERY different experience. Persona is a much more narrative spinoff series from the original SMT franchise. SMT games you are typically alone, with just a party of the monsters you recruit to help you. Consequently there isn't a whole lot of dialog. There is some story, but in most SMT games it tends to be very back-heavy.
SMT games do tend towards bleak, depressing and extremely difficult. They usually do have multiple narrative paths/endings to give it some replay value. They are really for people who enjoy those kinds of gameplay systems first and foremost.
