I stumbled upon some great wasapi performance while experimenting in linux a while back. I was playing Fathom modular synth, known to use lot's of cpu at times, and was shocked that multiple instances were playing smoothly. Also, the daws, plugins, and applications people use may have a wide range of performance good or bad, based on the skill of the multi-core-multi-thread coding that's available, and if the sundry parts in a session are optimally configured. The process of defining all that can be a buzzkill. Some things are great when set to single-core, and far less than great with even excellent multi-core daw settings.
I think your experience disproves a lot of cliche's, and also proves that well configured quality software and hardware, combined with experience, and knowledge, are to be preferred over old-wives-tales. There are too many production combinations available, to carve anything in stone anymore.
Could drive a mere mortal to set the beer-o'clock alarm an hour earlier...
Cheers
