Had a lot of luck with XP Home (Only thing that causes problems is the 3D screensavers, which for some totally obscure reason seem to like to crash my graphics controller seemingly at random...hasn't happened since first reinstall (A year since I got it preinstalled on this system), plug & play FINALLY seems to work like it's meant to in XP as well, which given the wacky selection of onboard hardware on this motherboard is kinda surprising.
Other stable OS's I've got here.
RiscOS 3.11 - in this case running on an Acorn A3000. (or to give it its full title "Brittish Broadcasting Corporation Archemedes 3000" - circa 1993. (Harddrive? Who needs a harddrive? We're talking fully GUI based OS here that's quite content with the OS in ROM, 2Mb of RAM, and a floppy drive...and an 11MHz ARM processor! To this day, I have never crashed that thing....and being ROM based means that a virus would be hard put to take down the system, harddrive data is pretty safe as well, I mean, how many people are gonna write such thing to attack an ADFS volume these days?!?
AmigaOS/Workbench 3.0. (1992/3 I believe...but I could well be wrong. Think that you either love Amigas or hate them, the former in my case, which is why I've got an absolutely mint condition Revision 1A A1200 here...which gets used for all useful things, and playing classic games...like Lemmings...which has a lot to answer for in terms of late submitted homework and college coursework! Occasionally it's been known to crash, but generally it's the web browser in my case, and that's an Alpha release...so doesn't really count. Has never lost a document on me though, unlike the PC.
Out of those three, which do I prefer, and what do I use them for?
Prefer: Amiga. Used for gaming, word processing/spreadsheets/databases/presentations etc, also using ProTracker to make music...which I am very bad at, but enjoy anyway...insane interface in that program though!
Most useful: Presently, due to compatability and present day requirements of the college computers - and the lack of a decent Amiga based web browser - has to be XP. PC gets used as a jukebox, net access terminal, and for more modern games.
Most unique: Has to be RiscOS.
