Can't go wrong with the Maverick 88 and most will recommend the field/security combo because it's 2 barrels for cheap. Keep in mind you're getting the 5 round tube in that combo.
Can't overlook the 20" barrel with the 7 round tube either.
Mossberg 500 only has the 5 round tube but it has a different (better) safety. I never actuate the safety on my shotguns so I don't care but maybe you will.
Neither of them are drilled and tapped. The 590 is drilled and tapped so if you plan to mount any kind of optic or do lots of shooting then buy the 590 in a configuration that you like and call it a day.
The 590A1 really isn't worth the $$$ and the heavy barrel is more of a pain in the ass than it is useful.
