I've got free subs to FHM and Stuff, and If I was forced to pick one of the two, I would probably pick Stuff. It has a few less advertisements (about 70% as opposed to FHM's about 85%), and Stuff seems to take themselves a little less seriously (if that's possible). But as others have said, overall they are very similar and if you don't like FHM, you probably won't like Stuff or Maxim, since both barely pass for reading fodder while depositing fodder, if you know what I mean.
