Which SC? Cerious GE or SR Atmosphere L2?

I have the opportunity to buy either a used set of Cerious Graphene Extreme or Synergistic Research Atmosphere L2 for $150 more. I have a set of the L3 as interconnects and love them, but I know there’s a big following for Cerious both for performance and price.

Both cables use Graphene, so I suspect sound signatures to be similar, but which one will produce more resolving and organic yet less fatiguing highs?

BTW, this would be going from a VPI 299D to the ribbons of my Alta Audio Lelantos. I currently use a much more expensive cable, the DH Labs Revelation SP (pure silver) but am curious about Graphene cables and like the idea of the Synergistic Research grounding system.

Thanks!
