Gen I is iconic but Blastoise falls a little flat. Not by that much though
Gen II is garbage with only Feraligatr being anything close to redeemable
Gen III are all great at the expense of a shit region
Gen IV are pretty dope
Gen V is pretty fucking bad, but Serperior has niche with Contrary
Gen VI are meh and Greninja's really the only usable one. Your real starters in Gen VI are the Kanto ones
So IV > III > I > VI > II > V
