Agreed. I had both at the same time. The Mossberg was far clunkier and rough handling then my 870. Sold the 500 and still have the 870 now for 30 years.
Love the 870. Bought one about 15 years ago.
Also have a Rem Model 31, the predecessor to the 870.
And a Browning humpback 12 guage.
And an LC Smith side by side 12
And a Rem 1100
And a Rossi .410
You can never have too many shotguns or coolers.
