I decided on PB Swiss w/Swiss Grips. I hope they're decent. I've had good luck with previous Swiss made tools.
Future warranty replacement may be problematic but my goal is to buy tools that never need warranty replacement. (vs. seeking out stores that make warrant replacement easy for their inferior tools). In other words, the best warranty is buying quality at the outset.
With my new car's extensive use of TORX (or so I thought), I went ahead and bought some Wiha drivers from wihatools.com. At first my eyes were playing tricks on me and I thought that the handles weren't on straight. After staring at them for a while and holding them, I just didn't warm up to the handles. I bought one of a few styles to try them out ('hard', microfinish, Proturn 3k), the fit and finish on all felt pretty sloppy (flashing, uneven paint, noticeable seams, etc).
The vendor sent a prepaid return shipping label without hesitation. I figured I could use some TORX drivers so I kept them. A few days ago I had a brilliant insight: all of the fasteners were actually TORX Plus (ugh). So I went looking for some appropriate (and apparently hard to find) screwdrivers.
I decided to grab a PB Swiss driver from Amazon and see how I felt. Without even thinking about it I liked the SwissGrip handle over the various Wiha styles. It just felt right. I like the color coding that PBS does. Neither here nor there but the PBS have thicker shafts and longer handles than the Wiha styles I tried. The Wiha handles were a beefier in terms of girth. In tight spaces or with big or small hands this may be an issue.
Obviously I can't evaluate long term durability with such light use over such a short period of time... so I still have some hesitation about long term durability of all of these soft handles, but we'll see.
You can get both PB Swiss and Wiha screwdrivers from Amazon (altho not the complete USA selection). If you want warranty service, pony up for a truck brand (altho my local SnapOn guy carries/warranties Hazet tools as well).
I'll likely end up putting the Wiha drivers up for sale in case anyone's interested.
