You can have adverse patterning with a full choke and steel shot. That is all I am going to say, because I don't want to start a steel shot pattern argument.
Since it is a gas gun, yes, you
should clean it more often. I have a Charles Daly VR-MC (1100 clone..sort of) and I rarely ever clean it and it functions flawlessly.
My roommate has two 11-87's (20 and 12 gauge) and he likes them ok. He has had some "trouble" with them cycling in the past, but then again, he does not believe in the concept of shotgun break-in; and imagine that: after about 150 rounds, they have cycled flawlessly ever since.
Also, with as brutal as waterfowl hunting can be on a gun, a cheap 1100 is not a bad idea.
