>>21620385They're not very good. Sure the games had a lot of content in them aside from Gates, but the content's not good enough to play anyway and the game is horrendously grindy once you get past the credits (again, aside from Gates)
A lot of people whined to the high heavens about Gates, but to Gates' credit, it at least had the first good story in pokemon which is more than what I can say for Sky (special episodes were pretty decent though, especially the second and last one) and especially for Rescue Team.
As I'm in a tiny minority who thinks that Gates is the best (I'd take the move levelling/paradise/better story/v-wave/mysteriosity feature over more content any day), I'd say the safest bet is Sky. Don't waste your time with Rescue Team, Sky's better than it in every single way
