Rocket - The mafia, BORING Aqua/Magma - Non-sensical goals Galactic - They looked weird Plasma - Stupid uniforms at first, then changed to rocket wanna bes
Flare had the best and most memorable admins, the most intricate story, and the most tense battles. Unlike any of the other teams, they're actually INVOLVED. My heart was actually RACING in the battles before catching Xerneas. No other game has done that to me.
Rockets - Considering how grandiose the later villains have become, simplicity can sometimes be a good thing. And I think, overall, the Rockets were the most successful with their 'plans'. BTW, this is original Rockets, the remnants from G/S/C were just bad. Aqua/Magma - Both plans were terrible and would have spelt doom to the world and themselves. I don't know what GF was thinking. Galactic - I think this is when GF jumped the shark. They basically want to remake the universe or unmake it. Plasma - Hypocrites and basically PETA. Make of that what you will. Flare - Y'know, after a certain point, I didn't care anymore.
I think Galactic > Rockets (R/B/Y) > Plasma
