I like the spas also, but that's because I haven't unlocked the m1014 again yet... spas has ridiculous range and with a grip you can hipfire accurately without steady aim easily. I'll have to try the 1014 after I unlock it, see what's what, because my only problem with the spas is when you come up on 2 or 3 people its almost impossible to kill them all, for me at least.
I don't usually have the problem with it. I like to plan my attacks though. Yesterday I hip fired behind two people got them both with one shot, one was a head shot too ; ) I recently unlocked the M1014 and was very disappointed.
