The 28 is one of my son's favorite guns. He has killed everything from quail to ducks with it. Never a problem. Many may not see the Waterfowl version with the composite stock as a great gun but they are about as low maintenance as it gets for a duck gun.
When you get right down to it most often the complaints are more a matter of style than function. Or lack of style to some. Bill Ruger made guns that worked. Function was first, ease of manufacturing was a close second. But they never wasted a lot of time or money on making their guns into a stylistic statements that others seem to think is more important than function. They are the 870/1100 mindset makers not the SX1, SX2, SX3 where the looked better than they function sometimes.
And while I am on "style" did you ever look at John Browning's guns. Most were all about function instead of style. Bill Ruger will be missed in the gun world. Few like him have come along in the last 100 years and I am afraid we will see even fewer in the next few decades.
