Don't mean to sound snarky but the best screwdriver is the one that fits.  You might have to shop around for some, might try a gunsmith supplier?  Guns usually have odd size screws that get marred if not using the correct size.  Only other suggestion is to be very careful with what you do have on hand.

I would say those made in Switzerland then either those made in Japan or Germany. The problem is getting screwdrivers that seat and fit properly as well as being durable so sometimes you need to go with metric sized screwdrivers to get a better fit to avoid screw head slop.

These are for wood screws, so not the correct thickness necessarily.  The important part is the faces are parallel rather than tapered.  So won't cam out as easily, less damage to screw heads.

I have been using the basic "sewing machine" set from Chapman Mfg. Good stuff but I do not have much experience with other quality tools. The small hand ratchet, and thumb spinner have made themselves very useful; especially with feed dogs and throat plates.

All the other posters are correct though, it is important to match the sizes and having a non-tapered head also helps.

Like others have mentioned, Chapman have a great range and are excellent quality. I bought them for working on firearms but find them useful for lots of other stuff, they have parallel sides on the blades and some are very thin, not always easy to find.

Those are called "hollow ground" in case anyone didn't know. Makes a huge difference when paired with the right size screw.

Those Chapman sets look good. 

I bought a Winchester branded set from a gun shop. Gunsmith sets are nice because they’ve got heaps of different size flat bits, and importantly they’ve got multiple widths, so you can get the right size without marring the edges of the hole the screw is in.

if you’ve got a good variety of hollow-ground flat heads then the rest are all pretty standard.

Extra-long shaft drivers are good for getting to needle plates etc. but are harder to find.
