This is not quite right (anymore).
Pulseaudio elevates the audio thread and makes sure that the rest of the system won't interfere with the audio stream.
Basically Pulseaudio does what so called "audiophile players" do. It does it on a system layer that's very close to the kernel. The PA configuration can be heavily tweaked.
There is an issue that comes with all system mixers and that's the resampling. Every mixer needs to resample to a common samplerate to be able to handle streams from different sources.
At this point you can configure your samplerate of choice with Pulseaudio.
This way you can stay bitperfect on your favourite samplerate.
You can even use high quality resampling algorithms with Pulseaudio.
Afaik you can't do that under Windows.
Fact is. Removing Pulseaudio from your system, usually leaves you with a (to a certain extent) broken system.
On my desktop Ubuntu I don't have any issues with Pulseaudio. My Desktop Linux sounds as good as my tweaked Windows 8.1.
On my Squeeze on Arch (SOA) installations, as well as Volumio and Rune - all of them are single purpose installations - you won't find Pulseaudio.

No, it certainly does not. There are Ubuntu variants - Lubuntu comes to mind - that don't ship with Pulseaudio by default. Lubuntu is far from "broken".
Neither do I suggest that someone remove Pulseaudio. Rather, following the instructions in the link simply allow the playback software to bypass Pulseaudio to avoid downsampling during playback in a way that makes setting up playback easier than digging into text files.
I too run Lubuntu and do not use Pulse. Pulse did not sound as good to my ears as ASIO with another Linux variant and my USB dac. Nothing about not using Pulse with Lubuntu causes my system to be broken from my point of view.
