Which champ is more viable in act 5

Which champion is better to get uncollected? Cull Obisidian or Captain Marvel 2019? I have both as 4* 3/30 and I want to max out one of them

Cap is better in the long run for things like act 6 while cull obsidian isnt the best option for things further on

4 stars are banned in Act 6.
