This, 2000 and 2003 server for me, i guess XP was ok too, once they fixed the majority of the issues it had on launch and added a basic firewall.
I really enjoyed XP-64, since it was basically 64-bit Server 2003 with a XP skin on top.
Never had much issues with drivers either despite its reputation, you just had to check there were drivers before you bought hardware, never had any of the driver crash issues.
Was still running XP-64 on my i5-750 until 2013.
