I have an old pc on which I've tried linux ubuntu and mint. Here's my findings:
-the installation is a piece of cake. Honestly...I'm kind of embarrassed in windows's name right now. All those versions (XP, 7, 8) want to overwrite each other. The linux distros just ask whether you want to overwrite them or add them to the multiboot option (and create a partition). It's as simple every OS should do it.
-I know this isn't universal, but no driver issues whatsoever thus far.
-I strongly prefer cinnamon over mate...haven't touched many of the other desktop environments, but I've gotta say cinnamon strikes a nice balance between eye candy and ease-of-use.
-ubuntu has gone commercial. Kinda sad, but it's very strange to have amazon shortcuts amidst desktop icons. Not sure if these can even be cleaned out. In any case, mint has my preferred gala of basic programs (firefox, thunderbird, VLC).
For emulator purposes...I'm currently messing with retroarch (pretty much all-in-one). I was just thinking of creating a thread when I figured the answer to very slow emulation myself (check the bottom of
this page). Right now it's a breeze for the cores I've tested (note: with my rig, I don't even bother trying PSX or similar). It's certainly worth checking out.
Pleng: I can agree that windows is more refined. If things work fine, they're certainly cool. But if you deviate from the standard a bit, it can be a daunting task to find it. I tested 2 monitors with different resolutions. It 'sorta' worked...the results got kind of strange, though. And the abovementioned video example is something I'm no longer used to doing.
Still...I've gotta say that with distros like these, linux is steadily closing the gap. Windows is still better, but light years? No way.
I also thought installing hardware would be a problem. I was TOTALLY WRONG on this. On the contrary: on windows, a driver for a printer is seldomly the correct one and from the website it always wants to install more bloatware than drivers (HP, I'm looking at you here). On linux, it just installs my stuff and that's the end of it.
(yeah, I know: with all these different hardware being around, it's hard to chalk up a definitive result on better/worse. I'm just stating my findings)
