Spray foam vs rigid foam for my container roof... I made a call

Had to pick between spray foam and rigid foam board for insulating my container roof in Austin. Went with closed cell spray foam because of the Texas humidity. Cost me $1,200 but the air seal is tight. First heavy rain came last week and zero condensation inside. Anyone here ever regret going with rigid board in a humid climate?

My buddy went with rigid board on his workshop in Houston and had mold starting to show behind it within a year. The moisture just found its way around the edges somehow. He ended up ripping it all out and going spray foam anyway, cost him way more in the long run. That $1,200 sounds like a solid deal for the peace of mind.

Yeah @theabennett, spray foam fixed my garage moisture issue too, best move I ever made.
