As others have said, it's the quality of the blades that's the most important factor.
However, I decided to treat myself to a recent birthday present with a set of VOH screwdrivers, they are an absolute pleasure to use (and have a nicer feel than any Bergeon, Horotec or AF that I've used).
But I also use various other screwdrivers where one of the VOHs isn't suitable, these are mostly tailored and dressed for individual tasks, here are about half of them :biggrin:
And also as others have said, shaping and finishing the blades is critical to maintaining good tools and reducing the risk of damage to scres and other delicate bits.
