Bitwig is native since so long, they had to find new challenges like CLAP
They are releasing fixes (for a already rock solid version) every 2 weeks.
If you want agility and wide compatibility, Reason is not anymore a logical choice in my opinion.
Yet again, they have a very unique offer with mind-blowing capacity and super creative (again only my view).
Either you can decide you don't care about the rest and be super happy with a fully integrated experience like only Reason can offer. Either you care about the rest and then I strongly suggest you to move to another DAW (I am in love with Bitwig and feel it has an edge on many aspects against ableton, in particular in term of speed of release and overall technical quality, but I am very much biased and Ableton maybe in fact much better
). ==> Moving to another DAW you will still be able to enjoy the super powers of Reason thanks to its Rack offer, to me it is genius move from them. But of course you loose the fully integrated/no-popup environment.
