I'm fairly sure I've seen 100+, although I'm really not sure of the exact number. As for manga... absolutely no idea. I'm sure that I've read much more manga than I have seen anime, however..
i'm not sure because i'm not in the mood to think about how many i've ever watched in my life but i can think of at least 5 off the top of my head, but then there's ones i saw when i was little which i obviously didn't know were anime cause i didn't kno what anime was back thenso i'm guessing around 10 or 11 maybe more.
i've seen too many to count...here are the ones i can remember...
