You are right that pglogical has more functionality. Much of that
functionality can be expected to trickle into core eventually.
One advantage of the in-core feature is that the initial table
synchronization can be parallelized, which can make the initial setup
faster and more robust. pglogical will probably support that too at
some point once PG10 is out.
