I have a 1/2" drive 12 point Draper set bought as a present probably something like 4 decades ago - I guess/hope there's a few more out there in their bright orange metal case
About half a dozen of the most used sockets have given up the ghost and been replaced with better "quality" ones so, for instance, I've a 6 sided Teng/Halfords Advanced/Draper Expert etc. I prefer 6 sided as they feel more secure/solid.
I now work on the theory that buying "quality" for something that gets used frequently or is "important" is a good way to go. So I'll avoid the set with 2 dozen sockets that I'll realistically only use half a dozen of and go for individual items.
