I’ve never used Pods, so can’t compare the two. But hard for me to imagine building a site without ACF; great tool, great support, great documentation. The developer has expressed support for ClassicPress and, I believe, his intent to continue supporting it.
Didn’t know Pods had a direct connection with Automattic, but I’d consider that reason enough to switch if I were using it. Just like abandoning Yoast for Rank Math, and TinyMCE Advanced for WYSIWYG Advanced.
