The old model Ithaca 37 is the best......I think you know that if you've handled one, worked the action and listened to it. The sound of quality and all steel. They're quick in reloading to the magazine and you can unload the magazine without working the action (these are important features).
Sorry, 870 fans.......I know there are a lot of you, but that's just because it's inexpensive and thus very popular.
But the old Ithaca 37 wins hands down on every count.
You can always make arrangements to have a gunsmith look it over for you to make sure it's working good and original condition. You'll never be sorry about buying a 37.
