Trap Skeet and Sporting Clays shooters prefer the 1100 over the 11-87. Seems that quality control on the 11-87s left something to be desired. They have a reputation as problem guns that may or may not be deserved.
Go to a Skeet or Trap shoot and see how many 11-87s you can find, they are almost nonexistent among serious shooters. Of course, you will not find many Mossbergs or Winchesters (Other than Mod 12 and Super X) either. Shooters who shoot a lot usually gravitate to the guns that will hold up and not give problems.
The most common Autos are the 1100 and Beretta 390/391.
Just my observation, take it for what it is worth
