I don't think anything comes even remotely close to the level of productivity and rapid experimentation / prototyping these DAWs can bring to the table.
It's not quite the same thing, but VCV Rack is making incredible and rapid progress into becoming a fully fledged DAW. I find myself using Ableton less and less and Rack more and more. Check it out!
Yes, I'm aware of VCV Rack and it is an amazing open source project. I use Bitwig Studio though, and having The Grid there (which is Bitwig's own modular environment, introduced in v3) is just too convenient to use another one next to it.
