Swarm.js or Meteor GroundDb?

[rogeriochaves]

I'm starting to work on an app that should fully work offline, allowing the user to sync it online even after several days being offline, there is nothing decided for the tech stack yet.

On one hand, grounddb is already inside meteor platform, that has built-in realtime syncing through sockets, same code on server and client, and so on.

On the other hand swarm.js seems to be more popular, have CDRT and so on, and it's not dependent of meteor

Both of them are in very early development versions too.

So, what are your thoughts? I'm not searching for a definitive answer, just arguments in favor of one or the other.
