Workflows are individual, and are used based on personal preference, which in turn is based on what an individual wants to do, what they feel most comfortable with.
While it's not my
own preference as a workflow foundation, I have absolutely no issues with a turn-key system like Radar - if someone feels that it gives them everything they need to do the best work that they can, then that's all that matters.
There's no doubt that computer-based production can be daunting at times - not so much with the DAW program
(although that can also be daunting at times as well), but more to do with the number of things that can happen inside the computer or the OS, and these things can bog you down from time to time, which can effect your productivity/creativity... OS problems, driver issues, software updates, RAM and CPU limitations, other programs running in the background... there are a myriad of potential issues that can slow you down that have nothing to do with the DAW platform in and of itself.
Dollar for dollar, I still think that a computer -based DAW - like Samplitude, PT, or Logic - gives the most bang for the buck, and allows the greatest amount of flexibility and expansion allowance.
But in the end, it all comes down to the
individual user, and the system and workflow that
they are the most comfortable with, because that comfort level and familiarity will generally afford
them the most creativity and productivity.
IMHO of course.
