I can't disagree, and I probably should have been more careful in my posting. I didn't mean to suggest that all Tektons are better than all ICONs categorically, or that Tekton sockets are better. I've super happy with my icon sockets for the reasons you mention-- tight fit, etc. I don't own any Tekton sockets, but the ICONs are some of the best chrome sockets I've ever used, nearly S/O tight and compact (and not full depth broached either, which I prefer).
I don't own any ICON combo wrenches, and I only have the Tektons in sizes 20mm and up where fastener fit is not critical (or rather, it's easier to achieve a good fit).
Rather, I had in mind the tool purchases I might make in the future, and I think I've about plucked the tree clean of all the ICON low-hanging fruit. IN the unlikely event I need or want to buy hand tools going forward, I'm probably more likely to buy the Tektons just because I think I already own all the ICONs of use to me.
The likely exception to that is more ICON pliers. I have the ICON flush cutters and they quality is amazing relative to the price. My flush cutters will cut wire the the size of a human hair cleanly and do it for $25.
I can see several more ICON pliers landing in my drawers, based not on them being better than Tekton but just being excellent in absolute terms. Some of them are Knipex grade it seems and cost much less.
