I don't know about 'the best'...
But presently my automatics are a benelli montefeltro 20 gauge (really my sons) and an older 390 beretta 12 gauge. i purchased both new.
On the plus, the action of the benelli is also much easier to open (easy for a youth to load). And, it's very light in weight (easy for a youth to carry). But, it's a recoil operated gun. The beretta is a little heavier gas operated gun. The recoil operation, by it's very nature 'kicks' more. The beretta by its gas operation doesn't kick as much. The remington you describe is gas operated too.
Supposedly the benelli is 'more reliable' under harsh conditions (eg duck hunting) because of few parts and a simplistic recoil operation. It's funny that the duck hunters I know seem to favor this gun for that reason, but then complain about the kick because they shoot all day with the gun...go figure
I wouldn't 'not buy the benelli' because of a little more kick (I know double negative). Break actions let the shooter absorb all of the kick and people have shot them well for years. I'm just trying to make you an informed buyer.
Oh well, my two cents from an anonymous person on the web. I'm not an expert and these are just my experiences and opinions. I'm sure a physicist could tell us how much force was exerted upon ones shoulder after shooting a monteltro at ducks all day...or you could just look at the bruise
I think both are great guns. I'd buy the one that fits the best recognizing that the benelli may leave you a little sore with prolonged shooting (clays, ducks, doves etc) verses a gas operated weapon.
