I can comment on the SOTA Cosmos, although not in a direct comparison to the tables you're eyeing. I ran a SOTA Cosmos IV for 11 years, first with an SME V arm, then later a Graham Phantom II (both 9" arms). I now run a Technics SL1200G with a Triplanar U12. The dd Technics is just way ahead of the SOTA, IME, based upon it removing a little coloration that the SOTA had, and definitely offering steadier speed (transients are crisper, yet natural, piano and organ are steadier in tone, just feeling "purer"). I did miss the vacuum hold down, but I've compensated by using a Stillpoints LP weight and a special perimeter ring that I had custom made - - they register the vinyl against the platter beautifully, except for the very worse warps (and the SOTA vacuum simply couldn't work on those, either). Oh, and I am using a thick acrylic platter mat instead of the OEM rubber one.
