To me they look like a proprietary modifikation to Torx that doesn't really offer much inprovements over Torx. Kind of like PH and PZ. The most annoying problem with metric and imperial screws are the #10-32 and M5, they _look_ the same but they aren't and it's easy to ruin a thread if you pick the wrong one.
