Felo and Vessel are my drivers of choice. For the European pozi drives and US phillips standard, I rely on the Felo (almost everything in the Frico 500 thru 550 series including the M-tec Mag tipped sleeves) line of drivers. The comfort and sure grip of these babies are unmatched IMO. Love these so much I bought their VDE (red handle) offering with the same sure grip and then went completely gaga and bought the Heyco/Felo (green handle) torx offering in the same handle.
After all of this I thought I was done buying screwdrivers, right? No, it turns out that Japan has their own version of the cross tip. If you ever worked on a computer or any Japanese product, you'll find our phillips std is a camming nightmare, because the standard US phillips doesn't seat properly in a Japanese cross head screw. The good news is that the JIS (Japanese Industrial Standard) design was made to work with the US phillips std. So if your looking for a better working relationship with your Japanese products, then my recommendation would be the Vessel Megadora series. This is Japan's high end version of the screwdriver and the US buying consumers best chance of getting the best quality, availability and price of Japan's JIS offerings.
I've tried dozens of name brand drivers with less than satisfactory results. I married myself to klein for a while until they started taking the low road on quality for profit. If you ever used the klein drives of 30 years ago, then you know what I am talking about. All of these experiences have helped me recognize what a precision tool feels like. Vessel and Felo drivers immediately strip away the doubts. I'm NOT telling you what you should be buying, I'm just saying.
With the ergonomic intelligence engineered in these drivers, you would be hard pressed to find a better option in both feel and performance. Sure there are companies that offer great screwdrivers, but Vessel and Felo are obsessed and built for one thing in mind...SCREWDRIVERS!! You want a great titanium hammer get a stiletto, you want a great driver....
However if you are not matching the fastener with the proper driver, then you have a far greater problem than the performance of any high-end driver. The tips, shaft and handles are perfectly balanced and sized for the fasteners for which they are intended. Exceeding these limits to the point of damage is not the fault of the manufacturer. Used properly, these precision instruments can last you a lifetime. If you think that the job may exceed these limits, then you may want to consider the industrial diamond or tin coated tips for over stressed applications. What you get in additional performance and durability out ways the initial cost. Less trips to your local hardware store and more time focused on the task at hand is it's own reward. The better drivers have a greater resistance to damage and exceed the limits of the lesser options. The High-end manufactures have the greatest understanding of these physics and engineer a greater number of drive options (other then the standard 6 drivers) to achieve the proper fit. Whatever screwdriver manufacturer you decide to saddle up with, keep the science in mind and exercise common sense when using any fastening tool.
