SpectraLayers Pro vs. Demix Pro

[M-K]

SpectraLayers Pro is at Version 11, DemixPro at 5.

Did anybody compare those? Which one does better stem separation (for remixing stereo to surround as one example)? Artifacts?

DemixPro is almost twice the price of Steinberg's SpectraLayers...
And there is the UltimateVocalReover Version 5.6, which you get free from github. Price is zero.

Please post your experience and / or opinion.

All this stuff changes on a weekly basis (The free public stuff anyway). https://mvsep.com/en seems to keep up faster than UtimateVocalRemover, even adding models made by the UVR team.

There are also a couple lists out there, where people go very deep into the weeds on all the available models.
