MongoDB used to suck in many ways. Since ver 3.2 with the WiredTiger storage engine, it only sucks in the ways that you'd expect using a schema-less document store. WiredTiger is kind of like InnoDB in how MySQL used to suck before it.

Using JSON with either PostgreSQL (JSONB) or MySQL is probably a much better bet. If you scale to the point that you really need sharding and not just multi-master and/or read replicas, then you can probably afford the migration.
