I have a Mossberg 500 and like it, 500 will not last as long as an 870 because the receiver is aluminum, but for your intended uses, your not going to wear either one out.
I have two Mossys that were given to me, a 20 and a 12. Neither were cleaned until about two years ago. The 20 (26" mod choke), I got a 13 and have put countless rounds thru it. Nice litte gun. It may wind up getting cut back to 24" and have tubes put in it.
The 12 has seen less rounds but is just as old. Neither have had any problems that were resolved by a thorough cleaning.
About the aluminum receiver, I worked on one that a resturant owner had. It was an older 18" pistol gripped cruiser that he had kept on a shelf above the fry vats. When the action was cycled it would lock up in the open position. I swapped all parts with new ones out of a current production gun. Jammed up with new parts too. Finally he sent it back to Mossy where they figured he had warped the receiver probably due to subjecting it to constant and excessive heat. And BTW cooking grease is a horrible lube! LOL!
Given that someone else is picking up the tab I'd say go for the 870. There are more options for it, depending on your intended use. Also the design of the Mossy mag tube precludes the use of extended mag tubes, if that is of importance to you.
