When you make your living from your tools, you want the BEST! Snap-on is the only way to go, Mac, Matco & others are good but fall short in most cases. Air tools are good BUT most line techs use battery powered tools for dis-assembly & assembly. I have a battery powered 1/2" impact that can remove lug bolts.
