The AK, M14, and G3 hopup I think are great. My SG1 was reaching out beyond an upgraded AUG (the aug had an M120 and my SG1 was stock), and my AK which was upgraded with the same parts was easily outranging the AUG. The M14, from what I've seen, has superblative hopup. I'd say either of those. The P90's is good too, and is better much better than the AUG.
