I'm torn between my nostalgia for the English openings and the much better animation for the Japan openings (the dub uses some of the same animation but replaces other parts with lower quality episode footage).
Though, I concedeJapan's songs weren't as shitty as some of the stuff like Battle Frontier and the pseudo-rap they tried to do with Sinnoh's first season. The lyrics of the latter still make me cringe thinking about it.
