They all wear out eventually, if you use them - but much more slowly than Philips or posidrive. Even a chewed up torx bit will still usually do the job - but a chewed up cross is useless.
I'd _very_ lightly push back on that for a posidrive, but it has a lot of asterisks. IF you can keep enough pressure on a posi, I've not seen issues. but if you can't it's failure case approaches the dreaded Phillips. And "enough pressure" is in the range of 170lbs of dude pushing down for really difficult situations in my experience, so yeah, "*"s abound.
