Hi, having had a workshop and needing to buy quality tools I bought snap on, despite having the option to buy Mac and having no real preference. 
 
 The reason was simply because the guy had a good reputation, was recommended to me, carried plenty of stock and was b****y helpful, just what is needed.
 
 Interestingly that is why Nelly maintains my bike.
 
 So I do not think the name matters so much as the guy selling them in my experience, hope that helps.
