Cons
Con Data are not on your server
Since it's a DBaaS, your data are completely on their server. It cannot be run on your server. Backup is handled by them as well, which may be good or not depending on your needs.
Con Not Open Source
Orchestrate is not an open source solution.
Con Vendor lock-in
Con No model mapper for Android
Couchbase does not have a model mapper for Android built-in and out of the box, instead you will have to write your own from scratch.
Con Not Compatible with couchdb
Since version 2 the sync-protocol is no longer compatible with couchdb. This makes couchbase nearly worthless
