I remember I used to be stubborn about learning Control Room too.
How silly I felt.
I never thought I would need that thing. It has improved every thing I do now from a monitoring perspective. The main feature for me though, is that I can run limiters, spectrums, VU meters, Limiters, Ozone and other things, just to listen in context, without running anything on my actual stereo buss. And that chain is retained for every song. Consistency.
