R3 5* Loki or R5 4* Guillotine.

So. I finally got my 3rd T4 Mystic cat and have the option to R3 my unduped 5* Loki or R5 my duped 4* Guillotine (sig level 68-ish). For those of you with more experience, what would the better choice be?

I haven't used a T4cc in a while and have a few in inventory now waiting for the right champs, I just don't get them often enough to blow on mediocre champs.
