Buy what one can afford. I don't think there's any disagreement there. I think most, not all, but most people can buy something above Hart at walmart or the cheapest amazon no-name. Which brings me to the conclusion below:
This is the mentality I have. People think my Wright wrenches are expensive. Compared to their $60 set, my wright-grips are. Can I do the job with the Sunex? Been there, done that, still have that 8-32mm set in my box. Point being I find value in the incremental improvement of the wrights.
That's really what it all comes down to - even if one is buying at HF, there are still cheaper tools available. So one is purchasing based on a matrix where price and marginal improvement both exist. As price increases, typically does marginal improvement, but it's obviously non-linear. Within that matrix, based on needs, available budget, and acceptance of cost, one purchases a product. In the example of buying Pittsburgh Pro, one has spent "more than required" to do the job as cheaper tools exist. Thus they've selected the marginal improvement presumed with those tools and spent the additional money to upgrade. This essentially describes all tool purchases above whatever is literally the cheapest item which can legally be defined as a "14mm wrench" for instance. Everybody justifies their place on this matrix. The issue being described in both this thread title, and conversely the "HF ***** brah" threads, is that even given identical situations people and their preferences/opinions/experiences/personalities are nearly assured to result in different results on this matrix of tools.
Supporting anecdote (the best kind of evidence) - My grandfather used SK tools. He was not a tradesman, he had a few sets of these SK sockets in the classic green case. "The tool box" as my father remembers it. Anyways I was in the market for a blow-molded case set of 3/8 shallow/deep sockets with some accessories for work away from the shop. I had purchased a Sunex 1/4 set already, and had the finances to buy whatever. I purchased these SK sockets because of HJE day, being (at the time) American made, and because they make me think of my grandfather. Someone with an identical life to mine aside from the grandfather connection may have bought.... proto, or tekton, or gearwrench. When looking at the matrix of tool,s people usually buy from somewhere within it due to a variety of factors which make it an "objectively correct" choice at the time given the inputs.
People don't buy..... Koken.... because of some giant spreadsheet of factors we can easily list out. They fell where they did on the matrix because of a variety of factors. So just because pittsburgh pro is my choice for impact extensions doesn't mean it's right/wrong, it just means it fit my variety of factors.
