Fibre ones aren't stock - they're MLS from the factory.
It's just that whenever the gasket goes due to the garage servicing the car not knowing how to bleed the system properly, they put on a Fibre one, then it blows again and gives XUDs a terrible reputation for head gaskets.
Seriously, in lower torque (<270lb.ft) cars, I've NEVER seen a head gasket go other than from incorrect bleeding or just plain old overheating it.
The biggest problem is when the gasket begins to go from overheating, they fill the head with air quite quickly and do airlock badly - once it starts going, it's a downhill spiral. Most cars would carry on for years with a slight weep... An XUD will just keep filling the head with air - once that happens, game over really.
