Did you mean "physical replication"? Logical replication corresponds to MySQL's model, I think, whereas WAL streaming is just copying over the changed bytes as they get written to the WAL on the master database. I like Postgres's physical replication for its straightforwardness. It's pretty easy to tell if your replica is up to date unless something really weird is going on. (undetected data corruption?). That said, PostgreSQL doesn't really make replication appear easy, so I can understand people thinking that even a basic master-slave setup is difficult (In my experience its behaviour is much easier to understand than with MySQL). However, MySQL is ahead in multi-master user friendliness, and setting up eg. a simple galera cluster is pretty easy. Whether an "easy" multi-master galera set up is actually production-quality is another matter entirely, but it is not difficult to get up and running.
