Rational discussion is good.
With the admission that this may be a little off-topic, I'll say that I have recently been experimenting with a Nova. There is a lot to like about this shotgun, although it has some limitations, too. One thing I'll agree with you about is that I immediately noticed what I'd describe as better gun mounting and fit. Those are personal tool/body "interface" issues, not QC issues. The Nova (and SuperNova) obviously don't have the kind of aftermarket support (among other things) that the 870 (or Mossberg) have. So...different strokes for different folks.
