I've never tried the Wiha wing-style drivers, but the Wiha stuff I own is excellent.
These are my go-to drivers for most knife maintenance. I think I had to buy one of them separately, but the rest came as a set. (
The Benchmade driver kit on the top left is quite old and not nearly as good, but for a portable little all-in-one option it's not bad.)
I also have a chunky Wiha interchangeable driver that's great for applying a lot of force in a controlled manner. Don't think I have a photo of that one, but it comes in handy too.
