I've had precisely the opposite experience - for me, JACK is amazing and gives me 40-channels of pro audio over my external audio interfaces (I run a studio with a Linux DAW), but if I put PulseAudio anywhere near this configuration, it dies in a burning pile of poo. I despise PulseAudio and will never use it.
