As much as I hate Sinnoh, from the voice acting to the region to its blandness, I have to say Sinnoh.
My Opinions Regarding the Pokémon:
1. Anime: OS > AG > BW > DP > XY
2. Movies: OS = AG > DP = BW = XY
3. English Dub: 4Kids Entertainment/TAJ Productions (EP001-EP276; AG001-AG020) = 4Kids Entertainment (AG021-AG145) = TPCi/SDI Media (The Origin)/Very Good > TPCi/DuArt Film & Video (BW001-BW115)/Average > TPCi/DuArt Film & Video (BW116-BW142)/Poor > PUSA/TPCi/TAJ Productions (AG146-AG192)/Very Poor > TPCi/DuArt Film & Video (XY001-Present) = PUSA/TPCi/TAJ Productions/DuArt Film & Video (DP001-DP191)/Atrocious
4. Games: XY > BW1 > BW2 > RSE > GSC > Y > HGSS > DP > RBG
5. Pokémon: The Origin: Excellent: 93/100.
6. TCG: Wizards of the Coast > PUSA > TPCi
7. Manga: RS > RB > Y > FRLG > XY > BW > E > DP > GSC
