Obviously all about personal preference but I kind of like buying these little bulk packs of the bits I use most:
and then I'll assemble what I want into these:

to leave in my toolbox. Buy buying them in bulk I don't care so much when one gets lost, just restock it in the holder and move on. Less annoying than buying a "kit" and seeing an empty space when one goes missing.
Also, I've never cared for the drill bits with hex ends. Feels weird to me. ;-)
