SRAM Eagle XX1 vs X01 and Chainrings

I'm planning on getting a Pivot Switchblade for next season and I'm agonizing about whether I should spring for XX1 for that gold bling.

Also, the Switchblade is going to be my first 29er after a decade riding 26". It's also going to be my first 1x drivetrain. I know I'm late to the party, but I really need those granny gears for those Colorado climbs! I really don't know what size chainring I should run. Want to see if any other eagle or frontrange riders have some opinions.
