As far as pumps go, the nova is hands down a better gun than any 870 made in the last 10 years.
Winchester has a new pump, the SXP I believe, that is really nice.
I'd go with a franchi affinity or beretta A300 outlander over the M3500. Cost a little more, but built better. The affinity is a benelli M2 clone and the A300 is basically a 3 inch version of the extrema 2.
