Your gun rankings [automatic controversy machine]

[civilized_person]

I see a lot of general concensus around a few specific guns, how good they are and how much skill they require. Some guns are just never talked about in that regard. So basically, I want to know your ranking of every gun from lowest to highest power (Pistols are ranked in their usefulness during pisol rounds) and lowest to highest skill requirement (you may specify floor and ceiling if you want.)
