I don't run pf-sources, but I run a BFS-patched gentoo-sources. One of the reasons I use it is because of its support for the SCHED_ISO process priority, which is important for audio applications. Otherwise, I would need to use a realtime-linux kernel, which is total overkill and I don't want to reboot into a different kernel just for an audio session. Also, SCHED_ISO works for normal users so I don't have to launch stuff like jack-audio as root.
Another reason I use it is because my system becomes a bit more responsive with BFS (meaning the GUI - I use KDE). You can do that with the mainline scheduler too, but it's not automatic; you have to set up the cgroups feature (creating different cgroups for different applications), and I never bothered. It's up to the distro to provide a cgroups setup, but I don't know whether Gentoo or any other distro actually does it. My guess is not. Without a setup, users have to launch their applications from the terminal, which is kind of stupid. Launching them from the GUI will place them all in the same cgroup.
So BFS it is for me :-)
