My least favorite is the FAMAS or TAR21, just because they don't fit into my play style, closely following are the Barrett, ACR, and Intervention.

Well, that applies to MP

for SP:

I dislike sidearms in every game, except MW, MW2, the original, and likely BO. Basically, I like the very first game, and the most recent games' sidearms, none of the rest.

I also dislike most weapons in CoD2, even though it's my third favorite, tied with the original after the modern warfares.
