I had a bit of a reaction to LP's stuff at first too but nothing's perfect. Pulse had its problems, but they got fixed. NetworkManager wasn't perfect (still missing Bridging support though I think thats coming in the next version, or at least the groundwork is), and systemd once upon a time would fail to boot every once and awhile. Bugs were found. Bugs were fixed. Projects improved. I can very confidently say now that on all of my arch machines, with varying hardware, I have zero second-thoughts about installing systemd + Pulseaudio + Networkmanager + Avahi. They just ARE the standard to me now because I know they DO work.
