Which 4* Mystic champ to rank up to 5

I have finally acquired enough mystic catalysts to rank up one of my 4* champs. I have duped Doctor Voodoo and Guillotine and an unduped GR. I do have a 4* awakening gem i could use on GR though i'm not sure if i should use it on a different 4* champ. Main question would be which to rank up to 5

best part of gr is you can redo all his judgements after a s3 so hes great for long fights since you can regen then use s3 and rinse and repeat and he is also bleed immune too and gets a little danger sense boost on villians (more crit damage and higher change to place judgments)
dv needs his dupe to get any good honestly so depends what you need
-gr would be my suggestion for you
I like the level of control you get for Regen/Nullify/Power Drain/Bleed.
Duping is just a bonus.
Seatin would say Duped DV all the way.
