I'm not taking sides, but even the "vst support" arguement is now full of holes.
Not saying these "holes' make one program superior(had to give the disclaimer), but Reason has done something they sought out to do...made vst support something that doesn't need considering within the program.
Back when this was a real issue, Reason didn't have audio input, didn't have the tons of effects within it now. But by adding so many tools to the program to get the job done, saying "Reason doesn't support vsts" since their later releases is like saying "a soley hardware setup doesn't support vsts".
They've given you too many other options to get the sounds you want at this point. And I don't even consider adding Rack extensions, they're not even needed. Most would just argue that those are your "vsts", it's equivalent to Pro Tools' HDM/RTAS systems, just not as many developers on board at this point.
Autotune, a Vocoder, Guitar Amps, Vintage Console Channel Strip Emulation, Dynamics/Mastering Processors, multiple EQs and Filters, mutiple Delays and Reverbs, and all at no loss of quality are at your disposal. When these things didn't exist in Reason, I was the guy whining about how there was no way of getting certain tasks done, but now, within the closed environment, nothing has been left out that you'd need in any studio environment.
I understand the guys who can't work without their "Waves Complete" or "REFX Nexus" bundles not understanding that...but anyone who knows the tools and can use what's put at their disposal can do anything within the program.
From 1 program, you get a mixboard, workstation keyboard, array of synths and effects to further manipulate the sounds, Drum Machine, sampler/sequencer, and effects for Mixing/Mastering, Processors Vocals, and live instruments. What more would you need?
