Need some advice

I'm trying to decide if taking a 5* gwenpool unduped to rank 3 is the way to go. My other options are a 4* omega red duped to rank 5, or a 4* archangel unduped to level 5. Some advice would be appreciated.

I know some people will say "you need to focus on 5*"
But unless u want to bring your 5* to rank 4 or higher, better choose champ that usefull most in same level
