In my case, the big advantage is the automatic insertion of resamplers between different clock domains, meaning you can connect anything to anything. Pulseaudio tries really hard to make sure there is only one clock driving any connection graph, so that's why there's no arbitrary connection support without loading things like module-loopback that add the resampling themselves. Another thing that helps is that in some ways PipeWire is less featureful than PA. For example, it limits the max audio buffer size to ~180ms which means it doesn't have to implement rewinds, one of the buggier features of PA (with the downside that power consumption can't ever be quite as low as PA).
