Which 3 star skill to 4/40?

I don't have a 4 star skill champ yet so out of these 3 stars which should I 4/40 first?

hawkeye useful with bleed and power drain

If you are like me and does not have a 4* power control champ, the next option is 3* version.

Hi all just an update, I duped my BP so does that change anything or does Hawkeye still stay top?

Hawkeye is the best and second only to gwenpool in skill but the bleed damage of blackpanther is also very good
and both are my one of favorite.
