I use Luna on my Mac. I’ve had good experiences with it, as it integrates really well with my UAD hardware.
No idea about Windows though. A thing to keep in mind is that all the UAD hardware is only useable with Thunderbolt. That’s a no-go with most Windows machines. Not worth the time and effort and what I think is a truckload of trouble shooting.
If I was on Windows, I’d give it a pass and look into something like Cubase.
