Backer Behind Kerdi

I'm definitely a Schluter system advocate but wondering what you guys use behind Kerdi. West Coast here, it seems my selections are limited, Gyp Bd, Hardi seem to dominate. If I need 5/8", hardi isn;t even an option. Never been a fan of gyp bd even behind even Kerdi (it's the old school in me, "never tile over gyp bd") but the Kerdi board is so crazy expensive. What are you guys using?

Drywall unless a customer demanded cement board. I used Hardi-backer occasionally. I estimate I've done nearly a hundred Kerdi showes over drywall.

As to the price of Kerdi-board, I've never paid for the customers material. They pay for it.
