This is tough. Like Codechimp said, it depends on the frame. But I agree, not a fan of carbon. I’d say Mars in X-Metal, Romeo in XM, Ti, or plasma, XS in plasma, Juliet in XM or Plasma, Romeo 2 XM or Polished. Penny in copper. The R2 is the only one I like polished. Overall, I probably like XM or Ti the best.
Kind of a toss up, as I love a good polished carbon too. I'm a heavy metal kind of guy, so black is always a go-to. But I think I like a good polished finish but a tiny bit more.
