I would go with the Remington 870. I have a Rem 870 SPS-T with thumb hole gun that I use strictly for turkey hunting and love it. I had the Mossberg 835 UltiMag and sold it to get the 870. The Rem. 870 is a tried and true gun...there has to be something good about it seeings how it is probably the most sold shotgun.

As stated earlier, the Rem. has a lot less recoil than the Moss. They both are great guns, but I would go with the Rem.
