Just what I was thinking CAG, the MG3 is just a slightly modified MG42 (no more wood, weights less, ...). Fires a little more slowly, but still twice as fast as the M60. Got to change barrels after 150 rounds though. (however every gun is equiped with 2 barrels, and it takes less than 3 seconds for a good gunner to change barrels and reload).
M60 was pretty unreliable in mud, however the video is indeed impressive. I haven't been able to test accuracy, the MG3 is superb there, but I would assume that the M249 is better. What I never liked about the M60 is the low rate of fire, its mainly a psychological reason, but a big one. If you've ever heard an MG3 fire you'll know what I mean (and dont try to listen to a video, guns sound very different in real). Those men who stormed the beaches must have been damn brave.
BTW: they say the Kalashnikov had an inventor, the MG42 came from god directly.
Sad but true: On D-Day there were only 5 MG42s which fired. They were credited with more then 5500 confirmed kills.
