The best - PB Swiss. Closely followed by Zephyr.
The good - Witte (German made), Wera (the regular ones, not the pointless “torsion”), Snap On and Apex.
PB offer a small discount if you buy a pack of 10.
Wera offer packs of 10, 20 or more at fair prices, but if you start using decent bits you won’t get through many.
They also offer packs with different sizes, which may be more useful for you.
Don’t know how Wera are priced for you though. They are “mid price” for me. You might be better served by a U.S. maker.
Consider buying from an industrial supplier (MSC?) rather than the box stores.
