Water starter fan
Kanto - personality wise (this was by far my fave version of Pikachu) and because they all had pretty unique + strong bonds with Ash, or at least the starters did
Kalos - cos they were all as fully evolved as you could get and imo the strongest regional team he had + liked the colour scheme of the team in general
Sinnoh was also great
