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.
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".
