I won't go out of my way to watch magical girl anime either, Madoka and Fate/Kaleid are the only ones Ive seen.
I enjoyed Fate/Kaleid more for it's Fate elements. There is probably something you don't realise about Fate/Kaleid, but I can't really tell you without spoiling it, but let's just say Kaleid isn't exactly a seperate entity or spin off show...
Season 2 is where shit gets serious so maybe you could wait until that has aired. (Or read the manga, lol)
Oh yeah, it's the final season of Misfits this year!
Little Busters I'm gonna get to eventually. Fate/Kaleid I'm still less certain about. I like Fate, but I don't like Magical Girl anime. If I do watch it, it will probably be on the holidays when I'll be swimming in free time.
Part of it is probably my indecision between starting from where I left off, or starting again. And at the very least I'd watch After Story before Little Busters, if only because it's a sequel to something you've already seen.
