idgaf about delphox tbh but fennekin is still one of the only other starters that comes close to tying with squirtle as an absolute favorite for me.
Snivy with the middle lead
Fennekin, because I hate the look of Snivy. Hated all 3 starters in Snivy's gen but finally went with Tepig, which made it the third generation in a row where I ultimately favored a fire starter (granted, gen 3 I fooled around with Treecko first and have sometimes used Mudkip on replays)
They're both easily the best of their generations but Fennekin is definitely better imo.
