I own Reason, BiaB and Studio One. I say „own“, because I do not use these things much.
But I see a pattern repeating in user forums.

Reason was born as a “Rack” of Virtual Instruments
BiaB was born as a Music Generator
And DAWS (IMHO a successor of the old MIDI Sequencer) are born as virtual recording Studios
Notation Software was born as a kind of “Word processor” for Music.
And so on …

In the Reason Forum, many users demand that the vendor should make the Instrument Rack a better DAW.
In the BiaB Forum many users demand that the vendor should make the Music Generator a better DAW.

I do not see this much with DAW users, maybe because in the analogue recording studio world you brought your musicians, your instruments, your notation and maybe some gear along. You just wanted to have enough inputs for the instruments and gear and enough channels to host the music.

Each of the vendors have a core business. And it is good advice to strengthen your strengths (the core business) and not to strengthen your weaknesses (e.g. the lacking DAW capabilities).

All I would ask for, is good interaction between all this pieces (e.g. MIDI, ASIO, MCP, ARA, to name a random few) and to enhance (when needed) the Core functions.
And that would a better use of time and effort.

Just my 2 cents.

If I use my stuff, I use the generator part of BiaB, the Virtual instruments from Reason (and others), Notation software that interacts with my DAW, a MIDI Controller that is nicely integrated and some very specialized tools (e.g. Melodyne) that behave as integral part of the whole setup. That way, each tool does what it does best.
