I don't have experience with the 1/2" drive ones, but we use the 3/8" drive Snap-on models at work all the time. If you can, spend the money to get the higher voltage. The 12 volt ones we have are pathetically weak, you're better off hand tightening everything. They also overheat easily, and getting them fixed is quite expensive.
