I own a supermag, and my buddy owns a nova. I don't complain about mine, and he doesn't about his. I've shot it, and it isnt half bad at all. I like mine cause it's an 870 (love those remingtons), and I like the front grip a little better. The nova's grip looks neat and all, and it's function of sliding over the receiver is interesting, but i prefer the simplicity of the remington. I haven't heard of any problems, so I guess just go and check em out, give a few pumps and shoulderings at the local gun shop, and find what feels better, and is more pleasing, to you.
