I use whatever gun I feel like; I don't look to the cod community for approval. If it turns out to be hated by the community, so be it. I couldn't care less if I tried.
Preach on brother.
I have all 10 create class spots and I use a different weapon for each one. I will rotate different guns in and out of the spots all the time. Then once I get one gold it moves to the rarely ever used pile.
This is the first CoD game, for me anyway, in which I didn't have a favorite weapon that I always went back to for some fun.
