I'd stick with Beretta, Browning, Remington, and maybe Winchester for gas guns. They all make 2-3/4" - 3" guns which will cover all your bases. I am a name brand kind of guy in this game. I have been fixing guns for a long time, and you can fix most any repeater - if you can get a part.
Pick the one that feels best to you. Don't be afraid of used. You can get a whole lot more gun for the money. If you're going to be doing many miles of walking and want a lighter gun, and don't mind a recoil operated, the Franchi 48 is in a class by itself in my opinion. I don't like inertia actions, but with the right loads they do work, but Benelli's go dear. I wouldn't trust a take off.
I am sure there's lot's of other folks who will assure you that a Brand X Whizzer for $399 like theirs is just the ticket, but you did ask for opinions.
There are no unbiased reviews or opinions. Take anything you read with a grain of salt. Maybe 100 grains.
