s**t I know way too many.
Which is why I didn't even try.
I'd pick a favorite series from what I've seen so far, but I've probably forgotten a series or two, and most of them have their merits in different ways. While most end up being school lulz, the ones in other settings always have different draws to them. Particularly when as much thought is put into that other setting as there is into character design.
[edit] All I can say is that my favorite male lead from a harem anime is Yuichi from Kanon, and Saber from Fate/Stay Night is arguably my favorite female character ever. [/edit]
@ AH: Arson is always the answer.
