Once I figured out how to get rid of the headaches involved with using Rewire and plugins that have latency, I am really, really happy using Rewire to let a DAW handle audio tracks. It would be pretty silly for Renoise to implement audio tracks (other DAWs do it way better), unless it provided a new take on audio tracks. But just sticking them in when Rewire does the job makes no sense.
As for the OP, if frequency of updates is a big indicator of value to you… Reaper is the way to go, for sure.
