I have the Mossberg 835 and like it a lot. I've shot the Nova and don't particularly care for it. I don't like the one piece receiver and stock or the feel of the gun. Can't say on the Stoeger. There is another that you may be overlooking and that's the Charles Daly. I posted a question on here for a friend and found out some interresting things about them...such as a lifetime warranty on all their guns. My advice to you would be to look around the gun shops and handle all of the guns you've listed. Ask some gunsmith's about the reliability of the guns listed. Good luck in your decision, but by all means get the one that fits YOU the best.
