1) Hoenn because fuck you, Cacturne is awesome
2) Kanto, to my surprise, seems like it'd be legitimately fun to explore. Johto is too rustic, Hoenn has too many water routes, Sinnoh is irritating as a location and Unova is too simplistic.
3) Sinnoh, though I hate the D/P/Plat games because of the Pokemon and the area, I liked all the gym leaders a lot, and while Barry was a fucking idiot he was at least as close to a competent rival battler as we've had, especially if you let him have Infernape.
In summation, I dunno, some blend of the three I guess.
