Tool help

Hi guys I'm going to college this fall for heavy equipment operation and maintenance and I'm going to be needing some tools. I got most of my stuff picked out other than the sockets because I'm stuck on 6 point vs 12 point? Which would you guys recommend? Do you see a lot of 12 point bolts in the diesel world where I would need 12 point sockets or would I be better off with 6 point so I don't round off the bolt? I need 1/4", 3/8", and 1/2" drive sockets in metric/standard and shallow/deep so...
