> Torx and hex is brilliant because you can easily say which shape of bit you need, and you'll instantly know if you pick the wrong one.

In my experience, a problem with Torx is that it is a common mistake to use a bit one size smaller than what it should be. It will still engage just fine, but if you apply too much force, you'll destroy the bit, or head, or both. I find it a lot harder to notice when I pick the wrong size Torx bit, compared to a Philips or Pozidriv.

I have made this mistake a lot when using Torx. I have learned myself to always test a bit one size larger than what I think I need, just to be sure.
