Your Two Cents: The Best And Why

Olympic fever has hit - athletes from around the world fight to be the best of the best.
Comic book fans know that being the best sales wise matters but so does fandom. How many times have books with average or below average sales managed to survive or come back from projected publishing death?

What book, that doesn't crack the top ten, is the best comic out there and why?
What is your favorite comic book underdog?






Thunderbolts. It has been amazing ever since Ellis reimagined it, and it looks to get even better after Secret Invasion. Ellis's dark humor was the perfect match for a team led by Norman Osborn.
Captain Britain and MI: 13. Even with the sales boost that SI is giving to a lot of the other tie-ins, I think this may remain an underdog.
It also had probably the strongest debut issue Marvel has offered in a long, long time.
