Going back and forth between the two - I use some 32-bit apps (3D rendering) that I run under Wine that keep me on High Sierra (though I will probably switch to Parallels when needed) as well as all the Adobe Creative Suite apps (PS, LR, AE, etc) plus Cinema 4D and a few other graphics/animation programs. So a real mix of software that has very different processing power needs. Trying to decide if stepping up to an iMac Pro would be worth it and/or needed. I don't make much money from my work but I am retired and have funds available to get the right system for the work I do, which would require 32 - 64 GB RAM, 10 cores (maybe?), and no more than 2 TB internal storage, since I have external NAS RAIDS available for backup and two OWC Thunderbays for online storage. I doubt there is a simple answer here, but curious what people's thoughts might be. Thanks for any info.
