I would say POD because it has a softer tone than most of the revalver stuff I hear. REV is usually more bitey (not in an EQ'd way) if that makes any sense, which makes it jump out of the mix more. It's pretty easy to get a decent sound out of the POD, the real work comes when you try and get it to sit in the mix, especially if there is a lot going on.
I like it though, good sound.
