Problem with multiple (same) champions in my roster. (Gwenpool 4* and 5*, Magik 4* and 5*)

Just today I duped my 4* Gwenpool. She's 3/30 Sig. 20. I have a 5* Unduped 2/35 Gwenpool already. Until the theoretical 4* Gwenpools max out the 5* is not strictly superior, am I wrong?
Then the opposite happens a couple of seconds later: I pulled a 5* Magik. Already got a 4* awakened 4/40 Magik.
I'm very happy, don't get me wrong, but I'm very confused. What I'm supposed to do with this new champions?

Depends on the Champ. Some don't need to be Awakened to be useful, but I would run the 4* until you have the Resources to Rank the 5* equally, and in most cases, I'd keep using the 4* until the 5* was Awakened.

I got my Magik awakened by a friend's recommendation with a class gem. Magik's signature ability is usefull in defense, but should help a little when attacking. Gwenpools signature ability is very interesting, preventing death by sp3 and reducing defensive ability accuracy. Two Magiks in a team could be usefull with certain bosses or quest that require heavy power control

One for Defense, and one for Offense.

Exactly. I don't see a future for my 5* Magik awakening. I love her power control. Great champ. 2 in one team could give me an advantage somewhere. Maybe the defensive ability accuracy reduction in Gwenpools signature could be usefull in some specific situations
