I have owned both, and in my opinion the Beretta is more reliable. I do feel that the Remington kicked me less, but who knows, that could be the way the gun fit?
I had a friend who use to go to Canada to hunt every year with some friends as they brought a total of 6 Remingtons with them. By the end of the trip the boat was filled with broken parts and only one gun still functioned properly.
Then they all purchased the Berettas one year, and did not have one broken part among them after they went on their yearly hunt.
Remington is a great gun, soft recoil, but for plain realiabilty, the Beretta hands down.
