I shoot all 3
Rem 870-20 IMO BEST UTILITY SHOTGUN
Moss 500-12 OK BUT NOT MY FAV
Ithaca 37-16 CLASSY PUMP LIGHT TO CARRY

Mossberg has given me numerous ejection problems(still trying to figure out)... Ithaca problems have been rare.. Rem issues have been NONE.

I would rate them #1 rem #2 Ithaca #3 mossberg

also shoot a BPS-12 that I would rate just behind the Rem 870. great gun, no issues with it except for me its a little heavy and bulky to carry all day.
