Favorite and Least Favorite Playthrough Teams

What are your favorite and least favorite playthrough teams that you've ever used? For me personally:

Favorite would be my White 2 team (Serperior, Arcanine, Swanna, Magnezone, Zoroark, and Flygon). It started out rough but ended up really good. I felt each team member contributed something rather than my starter stealing the spotlight (as has happened in some games). It did struggle against Iris's Hydreigon, but, I mean, it's Gen V Hydreigon. We all struggled.

Least favorite would be my Omega Ruby Team (Greninja, Swampert, Pikachu, Swellow, Mightyena, and Gengar) (I would have said my Diamond team but I didn't count that one since I never finished the playthrough). Most of the mons on my team ended up kind of...forgettable in a way, especially once my Greninja (starter transferred from X at Lv. 98) joined and pretty much dominated from there.
