I hated how everythign was slow in persons 1 & 2. And also how do dungeons work in persona 4? Is it the same dungeon you crawl through or is it mor elike zelda in the sense that you find dugeons and go through them?
In Persona 4, you have to unlock dungeons by doing pre-dungeon story line stuff involving a murder mystery. There isn't one dungeon you crawl through, there are multiple ones with their own design sensibilities. In that sense, Persona 4 is more like Zelda. Also, in P4, dungeons aren't pre-made, they're random and have specific gimmicks dependent on the boss. Like for example a sauna for a character going through sexuality/gender issues, or a strip club for someone who wants to break out of their isolated shell, or a dungeon where you keep getting lost and have to find your way to the end if they don't really want you there.
Battles tend to be fast, and if you're tired of dungeon crawling, you can always do simulation or role playing related activities.
