Run for the door or fill the gap?

internal promotion question:

GAMs and VP leaving the team resulting in big gaps to fill.  new leadership has serious red flags but I have a lot of leverage to advance my career by staying and taking over the accounts.  I would essentially be a "key person" in the middle of a shitstorm.

stick around with bad leadership, large accounts I understand and skip a level, or find better leadership internally/externally?

comp: would still be underpaid but value would significantly increase internally/externally.
