All the engines are stable but with Firefox/Chrome we distribute our own version of the browser; for IE we can only use what is installed so are at the mercy of corporate configurations and setup so it can sometimes be easier to get FF/CH running on PLM.

I don't know if there is any such statistics available, but I have to agree on that there are more things to consider when it comes to IE and that it might be easier to meet and match the code of FF since it's totally open.
That said - I've gotten all 3 to work and run for long periods without any particular maintenance.
Of course - you need to be on your toes when the host is updated, but that goes for any synthetic solution.
