I agree with you on this one!I consider OS/AG/DP to all be the same Team Rocket. AG/DP are my favourite Rockets anyway so whatever.
DP Team Rocket kept them (that is, the trio) relevant through contests, and they had souls and funny moments. They also didn't get in the way of Team Galactic's amazing story. BW Team Rocket are very boring with no personality, and they completely replaced BW1's Team Plasma in favour of poorly written Pokémon stealing or legendary controlling episodes. Even if the earthquake never happened, the entirety of season 14 was planned out and there was only 1 Plasma story and lots of terrible Rocket ones.
