At least they have brains in the manga.
You'd think by now, the anime characters(yes, Ash, I'm talking to you) would notice idiotic Team Rocket. The only thing Jessie and James are good for are a few laughs and RocketShipping. Giovanni at least has a brain in the manga and would've fired them, probably in the first season, too.
The plot is a lot better, and not repetitive like the anime.
Anime: Oh! A new Pokemon, a new friend/rival, a battle, Team Rocket blasts off again, ending in the sunset and continue on their journey...
Manga: Something happens and domino effects everything else to where I can't explain because, like I said, it's not repetitive.
Meaning:
Manga > Anime
