I didn't actually know about PouchDB but it looks very useful!
I think the main difference here is the use case. remoteStorage is not intended to be used as a database (just like localStorage is not intended to either), but rather to store non PII data such as preferences, impression events, etc. without having to roll and stand up your own DB and API.
