Windows drivers are the ones with limits on how many GPUs you can use per brand (usually 8 sometimes less), not LINUX.
Windows is more user friendly (except
for most users, and has better tools for fan control/power management/overclocking - there is no LINUX equal to Afterburner.
LINUX is more stable and far LESS crash prone.
My "big rig" ETH miner (3 x R9 290, upgraded from an "Avatar" Litecoin mining rig) went MONTHS at a time without downtime, I'm pretty sure the only downtime it EVER had was when I physically had to move it or when I had a power outage.
Several of my other LINUX-based mining and crunching rigs have managed even LONGER uptimes, back when I was still in Iowa and was in the same place for the last 8 years or so there - often measured in YEARS between power outages.
I've NEVER seen a Windows mining (or crunching) rig go much more than a month without some sort of a crash.
For reference - when I say "crunching" I'm usually talking about the Distributed.net cryptography project, which puts pretty much identical stresses on a rig for the SAME reason that cryptocoin mining does (less I/O usage though).
