You are 100% correct that it's just an opinion. But it seems like every time someone brings it up, someone else also insinuates that any 'professional' shop or mechanic that uses Harbor Freight tools is a hack. It's not an opinion, but fact that that there's some very exceptional technicians performing superb work with some low-grade tools. But unfortunately, there's also a bunch of hacks too, lol.
I'm not trying to continue a debate here, just a friendly discussion. Truthfully, the vast majority of my tools are Snap On, Mac and Cornwell. I have a lot of Craftsman stuff too, but that was just my budget home stuff, before I brought all my work stuff home. Then there's the assortment of Harbor Freight stuff, most of which was purchased when I worked at the shop. I've been called a tool snob many times, but the HF stuff shows that I'm open minded.
