Looks like you have about 100 nights. For Marriott, assuming its $100/nt and you are plat that would be about 150K points, 200K with the card. Almost enough for a trip reward which is the sweet spot of their redemption (7 nights plus ff miles).

I'd lean that way, depends on how you like to redeem. The AXON gutting takes the sweet spot out of HHonors.
