I split pretty evenly between Bitwig, Logic X, and MuseScore and I can tell you the first big reservation I have with something like this is that it's an online DAW.

What does that mean? It means that your compositions (outside of bouncing them down to audio stems) exists within a highly proprietary SaaS format and that the moment you stop paying, you've got NOTHING.

99% of major DAWs (Ableton, Logic, FL Studio, Bitwig, Studio One, etc.) are a perpetual license.
