Good to know about Vessel, Tbh I have no experience with them, only just by what I read and I do like them by what I see & read. I use to restore bicycles and while tuning them it was apparent that JIS screwdrivers were far better than my euro and american drivers, Shimano screw heads just didn't like them so I bought a jis set and was very happy with them on bikes but its been 10 years since really working on them. The JIS drivers were not good on american fasteners.
PB Swiss is a great company that few can match in quality and materials, we need more companies like them. My PB slotted's have worn out, my 3.5 & 4mm especially; maybe I got a bad batch, I did have to return a third one because it had twist badly after just 1-2 uses, the Felo had no issue on same fasterner/machine. No questions asked and I got a new one but that one is wearing not twisting. I like their handles a lot, they're like a rock hard sponge and the grooves in them give you good grip and torque, although I find the Felo's more comfortable for longer use. The phillips heads on the PB's have no sign of wear.
Agree with the above getting PB's with with hexagonal shaft but they're super pricey ($130 for 6) and not offered in sets so you have to buy them individually and they don't offer them in sizes larger than 8mm (under 3/8") slotted which is odd since they make a phillips #4. A 10mm slotted can get a lot use especially with a hex shaft.
In my machine shop I have the jigs and tools to profile the slotted blades back to being crisp and flat/perpendicular. I do this often with my watchmaking drivers and you'll notice a night and day difference when freshening up.
The SK soft grip drivers are great, they are the same as the old Craftsman Professional drivers that are no longer being made, pretty silly to see how much those are going for on eBay but I still have a 1/4" inch that I really like to use and refuse to retire it. They have similar tip profile as the Williams, the Williams were a bit stronger.
I also have the William/Snap-On driver set and hard not recommended them, The price is awesome for what you get (huge sets), there tough and you can just beat the hell out them. For the price, they're great. The squarish handle gives you a lot of good torque with with those big corners. A good American tool.
All of this can be so subjective. The grip, length, weight, balance and profile all have influence on what you think of them, a lot of it can be a personal taste, attitude and also importantly what you're working on (the type of fasteners). I do like my Felo 550 4mm much more than my PB Swiss, and I have a precision 4mm Wiha for when a carful light touch is needed.
