I would have to give my vote to Colt. I own a Colt LE6920 SOCOM II and it is superior in workmanship to the my other AR, a CMMG. At least until I started throwing $$$ at the CMMG to make it not suck, but now it isn't really a CMMG anymore. Ha ha ha. Even now the Colt is superior in many ways, mostly in the bolt carrier group and bolt department.
While in the Marine Corps I had issued to me several Colt M16's, all the Colt's were A2's and my last M16 was an M16A4 made by FN. The Colts had noticeably better triggers, better finish machining of internal parts, ran smoother, and seemed to be more accurate (at least the ones I had that didn't have nearly worn out barrels). The FN's trigger was so bad that you could lift the rifle by the trigger with optics, a PEQ2, a light, and a full magazine on board... and the sear wouldn't trip. Not impressed.
