Go GP. She has more overall utility than killmonger, also God tier.
Couldn't find killmonger on the tier list, but I'm assuming he's top half, but not god tier. Gwenpool outranks pretty much every other skill champ (with the exception of Blade), so I say her.
Killmonger is high demi-god. I've seen videos and asked advice. Gp is great and all but killmonger for example is a rlly good counter against evade champs, auto-block champs(especially like medusa and modok) and can tank sp3. Also has that sweet sp3 ability. Again GP is god tier but killmonger will be more useful on the aw aspect. Now IDK if the same thing goes to act 5. Im super close to collector and I only have 4/40. Except my 3/45 AA.
Honestly I would go for killmonger if they are both 5*s. He is so useful in AW it's ridiculous. If one is a 4* and the other 5* go STRAIGHT for the 5*.
