It depends on what you're doing. The Surge driver delivers a lot smooth drive with more control. If you are hanging some drywall and trying to get the heads of the screws just below flush without going through the paper like you should be doing, the normal Fuel hex driver is a lot harder to use. Tends to under or over set them, with the Surge, very easy to control the screw depth. It doesn't have the brute force of the other one, so that is good and not so good. We use it a bunch with long extension to pull and install the small driveshaft strap bolts. The non Surge tends to snap them off once in awhile, the Surge doesn't.
I build crates for shipping stuff from time to time and getting the screws flush set in the plywood sucks with the non Surge. The Surge just works stupidly well for that and the plus is the bits last longer before they start camming out of the Phillips drive. Like most things, if you're using the wrong tool for the job, you'll think it sucks. If you're smarter than the tool, maybe not so much. ;)
