My first shotgun was Remington 870 20 gauge which I still have today. I was just adding up the years and I figure I've had that gun for about 22 years. Of coarse I don't use it as much now, but after shooting my other 12 gauges I can pick up that little 20 gauge and it just falls into place. So I like the 870. I realize a 20 gauge will feel a little different than your supermag but they should be somewhat close. If you are sastisfied with the remington and like how it feels. Why not get another one? If not or you want totry somethingdifferent getthe Nova. Yep you probably couldn't go wrong with either one. Hope I was some help. Good Luck!!!
