I'm confused by the idea that torx could be superior. I don't think I've ever touched a device or car with torx heads that didn't end up with half of them being stripped.
I have tinkered on cars both with and without torx.
Torx sucks, its also not uncommon for dimensions to differ on included torx tools so when you use a size 3 on another products "torx 3" it will strip away.
"Included" tools are expected to invariably be of shit quality. Blaming a fastener standard because of whatever some random Aliexpress vendor is doing is rather stupid.
Also a T3 would be 1mm, this is like mobile phone fastener size, nothing on a car is a "size 3", so QYBS, you do not have any depth on the subject matter to have a useful opinion.
Use quality tools, there is absolutely no problem, there's even an ISO standard (10664), there is absolutely no reason for ambiguity. Just stop buying shit.
Torx has tremendous benefits which is why it is a fastener of choice for high value items on cars. They're also used in high volume construction, they wouldn't be if they "sucked".
