Preferred audio module for jack audio

What are other linux users experiences / preferred setups?

I recently gave up using Jack at all (I liked Jack’s approach at first, but in practice I find it tedious to set up and use, and I got tired of the issues with my system). I’m now using Alsa as the audio driver for Rack and I get noticeably better performances. Update: in general I got mixed results, but I’m currently using Jack, more details here.
