For me, it came down to the controls between the two.
I really liked the safety location on the Mossberg and I think that it is easier to manipulate, especially if you are wearing gloves in cold weather. Also, the action release on the Mossberg felt more natural for me. I just move my middle finger slightly forward and I can engage it without interfering with my trigger finger placement at all. Basically, with the Mossberg, for me, it was much more ergonomically comfortable and I could manipulate all the controls without moving my shooting hand placement on the gun. For those reasons, I bought the Mossberg and it has been 100% reliable and accurate as well.
Both The Remington and Mossberg are good guns. Go handle both of them and manipulate the controls, see which feels better to you. You can't really make a bad decision between the two.
