I would trade for MB.
I used to own a MB. It does get easy but the shots, sounds, modes are very satisfying. I've played just over a dozen games on AMH and RZ. I'm a huge supporter of what Spooky is doing - but don't find them as enjoyable as MB. They still feel a little "home brew" to me. Fun games, but something I can't put my finger on feels less complete.
Whatever brings enjoyment go for it. I would lean towards MB though.
