As for my views on what's been done better than any other saga:
- Animation. This is the best animated saga to date.
- Villains. I agree with Pokemaniac24; Unova!Team Rocket is the best evil team the anime has done.
- The pace. It's got an even better pace than Kanto and Battle Frontier had.
Other than that, I've got nothing. BW does alot better than Johto, Hoenn, and all of D/P, but Kanto, Orange Islands, and Battle Frontier have also done these good things, and sometimes better. And please note that this is in no way a slam against BW, since I love it, and I shall eternally shake my head at all the people in this fandom who don't.
