Having experience with running both, I would recommend GoToSocial instead 😅

Akkoma isn’t too heavy, but the setup is a bit convoluted and there is almost no support what so ever if you run into problems.

Hubzilla has interesting features, but use as an AP fediverse instance is an afterthought at best. It kinda works, but if that is the part you are most interested in, I would not use Hubzilla for it.
