Question about spray foam vs batt insulation in my 20ft container | Container Homes Builds

I insulated my first container build in Tucson with regular fiberglass batt and it was a total pain cutting around all the corrugated ridges. Last week I helped a buddy do his 40ft with closed cell spray foam and the difference was night and day, it sealed up every gap in about 4 hours. My batt build had condensation dripping down the walls by the second winter but his has been bone dry. Anyone else made the switch? Curious if the $1800 price tag on the foam is worth it for my next one or if I just did the batt wrong the first time.
