Linux vs. xxxBSD

[Michael Hipp]

This is not intended to start a flame war, honest, just wanting some 
informed opinions...

I have an upcoming web application that will be pretty intense and based 
around apache with a database backend. The server(s) will be headless, 
tuned for the job, and no desktop apps.

Is xxxBSD really more stable than Linux?
Is xxxBSD really a better performer than Linux?

I'm asking because that is the contention of some ISPers I interact 
with. Don't particularly want to learn xxxBSD, but would if the gains 
were worthwhile - I'm a Red Hat guy at heart.

Any thoughts appreciated,

Michael
