I've got quite a few PB Swiss tools.
Started buying them probably 15 years ago after I was given some old ball hex drivers. Although they had obviously seen a load of use there was no noticeable wear and I was dead impressed!
I used to work in the armament industry in the U.K. and tools like pin punches and Allen keys get a lot of use. The P.B. Swiss, or P.B. Baumann as they used to be known, held up better than anything else I had used before, or have used since, and are without doubt my first choice if I need anything that they offer!
I met Max Baumann (the owner of the firm) a few years back and he is a true enthusiast. (He'd fit in well here). The level of research that the firm undertakes is awesome, and I learned a lot just from speaking to the guy!
The only downsides to the product range are, firstly, that the majority of their tools are metric. They do offer some imperial sizes (hex keys being one of them, 1/4 inch screwdriver bits being another) and where they do I would acquire them in preference to anything else! Secondly, many of their newer tools are designed more for the electronic industry and incorporate feature such as soft handles that are totally unsuitable for workshop use!
This can generally be got around, as there are more suitable products available in the catalogue! These rainbow coloured hex keys are an example! They do look good, but bear in mind that they are powder coated (I believe) and this will eventually wear off! I suspect the majority of contributers to this forum would be better served by their regular chrome plated lineup, which will have an awesome working life!
It's worth looking at the catalogue, if you can acquire one, or the website if you can't! There is some superb stuff in there. If you get nothing else, just get yourself a screwdriver, or a simple non ratcheting bit driver with a hard handle and see how it works for you! I suspect you will be back for more!
