Personally, I use Nextcloud, running on one of my home servers. For SaaS storage, I honestly dont' know. I don't use Nextcloud to have instant access, I use it for redundancy for critical data that I don't want only living on my phone or laptop (like tax and legal docs), but that's also data that I don't want to hand to a third party app willy-nilly.
