I wouldn't call it much less usable, depends on what you're used to I guess.. Actively using both, each for their own task, I find them on par with each other. But I don't expect Windows too give me a super easy to setup server with a mighty commandline, and I don't expect Linux to give me a super smooth Desktop UI that can be used as a digital audio/video workstation, for instance. Cause they both suck at those tasks equally as it's far from their target experience. And I also don't have the WTF feeling you have as I never had the problems you talk about: three minutes? Really? More issues than Pulseaudio? Almost sounds like you try to run Windows 7 on an old pentium with crap drivers :P
