Putting preference aside, I really think Orphans beats all other Gundam shows in terms of execution. They know what they are trying to do and doing it well. It's much harder to find glaring faults and far easier to point out highlights in this show.
I love the fact that Mikazuki's kiss probably saved Kudelia's life. If it weren't for that scene, Fumitan could very well have followed orders. It was that show of cuteness and innocence that pushed Fumitan (seriously, I love this name lol) to save her.
