#2 Phillips Screwdriver Showdown 

I work on atv's quite a bit, along with everything else, and the screws on Japanese ones are all JIS head screws. The Vessel brand are all JIS tip screwdrivers, made in japan and high quality. They've become my new favorite brand driver. I've got a set of the Megadora impact screwdrivers, a couple of different size Megadora chissel screwdrivers, the plastic clip removal tool with a Megadora handle and, im getting the Big set of red handle Megadora thru-tang screwdrivers. They work just as well on regular Phillips head screws, too. I really enjoy using the impact screwdrivers on powersports carbs because if it's older, the screws are always stripped out from people using regular phillips tipped drivers to take them apart.

Those Pittsburghs are the WORST. Shaft is too skinny. They’re mushed into those triangular handle at all sorts of ridiculous angles. The WORST screwdrivers I’ve ever used. And so, like you, I went on a mission to find a better set by buying one of several different brands. My favorites, so far, are by Wiha. I REALLY appreciate the power I can get on the handle. They’re the best handle/grip/tip combo I’ve come across. The Vessel tips are amazing!

Didn’t think the vessel screwdrivers would be counted, as they’re JIS not Phillips

It's not clear why you chose to stop with a lot of the screwdrivers, the drivers weren't camming out or stripping the screw heads or anything, so I don't really know what this test proves.

You forgot klein

No Klein tools? :(
