Hmm I generally have had bad experiences buying out whole sets. I just buy what I need and get the best possible ones from now on. For eg, have 3 different brand nut setters (wiha soft grip, hobbypartz crap, AE which is the best of the rest) before I settled on a hudy which is the best of the lot
for RC. The wiha is too shallow for shock screws etc and the AE looses the anodizing easy. w.r.t. drivers, had a hitachi bl-3 or something, which died in a few months so went with the makita which runs great for the past two years almost! Again could have saved some money there buying the best!
The MIP 2.5 ball end does not wear out like others, I use it to remove engines from quick mount type engine mounts wherein a straight end driver strips. Checkout your local fast guys tool sets, most are not sponsored by tool makers so they buy the best of the lot
