Who to R2 (or R3)?

Thanks to the Necropolis I have TWO Generic R2 greens, and a host of 7* champs to choose from. I also have a cosmic R3 gem, prompting me to make both 7* class crystals cosmic, and got Silver Surfer and Terrax. I feel like I've got 4-5 equally good options so would appreciate some guidance, please, particularly where awakening is a big factor as I've no guarantee to awaken anyone here any time soon, let alone further increase their sig level.
Options as follows
Bishop feels like a frontrunner, but maybe between him and Sunspot? I love using Wiccan and Morbius, but their lack of awakening concerns me. As for the cosmic potential R3, Vox might be the best, but again without his awakened ability...? Am I better just to wait? I haven't even started act 8 so Valiant is a long way off.

(Except exploring Necro and pulling him from the selector, that is… 😅)
I suggest you to try black cat, she's amazing for bgs and questing, Also wiccan is a great champ too.
He still give some people issues in BGs and is actually packed with utility on offense (loads of armor break, shock and bleed immune, immune to power burn against #metal champs)
I am path 3 in AW and usually do the whole thing with just Terrax (depending on defenders)
With rock field up, stack some armor breaks, throw a relic and land a heavy for pretty yellow numbers.
I took Black cat to R2, she was a monster in the VT meta last season
Who would you personally prioritise out of those two, barring a convenient awakening?
