Dexterity.membrane advice


I'm using dexterity.membrane for the first time (on Plone 5.1). And just wondering should I make my user type folderish or use the (old style?) "Member area type" under portal_membership to set a custom folder type.

I'm even wondering whether to use both! Keeping the "Member area type" for content that might outlast the user on the site, and content under the folderish user type that gets deleted when the user leaves (or requests deletion under GDPR).

Would anyone with some experience using these things care to comment?
