Unholy DK Puzzling Cartel Chips

Hello everyone! Got myself three chips again, and was wondering what the better purchase is for Unholy DK. I have the choice between Myth-Track Pacemaker and Hero-Track Astral Antenna. I already have the Cursed Stone Idol as Myth, as well as Fatebound Crusader.

There is no chance at unlocking Astral Antenna as Myth, as I do not really raid.

Any advice would be appreciated :) Thank you!

Edit: Question got answered, listened to advice to sim and settled for the Pacemaker! :)
