The question is pretty simple, which comic uni/multiverse do you prefer and why? Perhaps if you got a favorite character in either of those, you can name that one too.
I personally prefer Marvel, predominatly X-men. My favorite character varies quite a bit, though Nightcrawler is one of my favorite.
