I've got Wera [laser tipped & chiseldrivers], Wiha [extra heavy duty & microfinish heavy duty], Matco [rebranded Witte], Felo Ergonics, Channellock, and Greenlee drivers. Just ordered some Snap-On Instinct's yesterday. My only two ratcheting screwdrivers are Snap-On as well, which I just recently picked up.
All my screwdriver sets are pretty "comprehensive" you could say, with my Wera assortment prob. being the most complete...torx, nut drivers, full-range of slotted, stubbies, ph1-ph3, precision drivers, esd drivers. But generally, most of my screwdriver sets will have the most common slotted and ph1-ph3 and a bit holder w/bits.
Seems like I've got quite an assortment of drivers, but they're all used frequently and I've found it's easier to keep separate sets in varying bags/boxes based on jobs, travel, etc.
Thankfully I've never actually paid full retail on any of my screwdriver sets, or else I'd be out quite a bit of money!!
