Should I get Marvel Fluxx?

Ever since I started play Monty Python Fluxx and Zombie Fluxx a couple of months ago, I have enjoyed them.
So when I saw Marvel Fluxx was being released in a week, I got very excited.
However, upon further inspection, I realized there aren't going to be any creepers.
Since I've only ever played Fluxx versions that rely on creepers, I'm not sure how a version would work where they are nonexistent.

Anyone would has played noncreeper versions of Fluxx, what did you think?
Can anyone say if versions with creepers are more fun?
Is Marvel Fluxx worth getting?
