I have not seen or heard of a bad Linux distribution.
We started switching to Mandriva on all our PCs a few years ago and have never looked back since then. We chose Mandriva then because we thought that our learning curve would be flatter with this distribution at the time. (In retrospect all effort went to learning the Linux fundamentals and way of thinking and not so much on the particulars of the distribution).
Most of the machines are set-up as dual-boot to run existing Win32 applications (mainly CAD and accounting) which we have not yet managed to run under the Linux
WINE environment.
Blue screens are now distant memories to be told to grandchildren like black and white TV.
