Wright does not offer a complete 1/4 set with everything I want, they also don't currently make a 1/4 sliding T so I have an old Craftsman.
If I bought their 35pc set for say $250 I'd get a 4" extension some bit sockets and a few 12pt sockets that I really don't need ,I would have to spend about $140 for the metric sockets.
Buying my stuff individually I came out ahead by about $40 , basically not paying for those 12pt and bit sockets I don't need.
Proto - 37pc, sliding T, flex extension, spinner with female drive, can be had for about the same price as the 35pc WRIGHT set.
William's- 38pc, sliding T , flex extension, spinner handle has female drive but I believe it's Taiwanese, cost just a few bux less than the 35pc WRIGHT set.
And on to SK
Set #1 - 44pc , ratchet, 2 extensions, 41 sockets, no universal or other drive handles, average $60 less than the 35pc Wright set
set #2 - 48pc, 41 sockets, ratchet, 3 extensions, 3/8 adapter, universal, palm ratchet, average about $50 less than the 35pc WRIGHT set.
Set #3 - 60pc, 54 sockets, ratchet, 3 extensions, 3/8 adapter, universal, average $30 more than the 35pc WRIGHT set.
