Like Yu said, it depends on what Persona aspect you're looking for.
The closest game having the Persona formula would be The Legend of Heroes Trails of Cold Steel (jRPG mechanics, school, social life, no modern setting though)
I'd say that Danganronpa games always reminded me of Persona games the most (especially P4G). Those aren't RPGs, but the mystery, school setting and social elements have that Persona feel to me. I've seen a lot of people comparing the two before too
Mind Zero is a Persona rip off but it's a mediocre game
