In general I have issues with the Azure documentation. I can't put my finger on it as to why, but for some reason the information doesn't seem to be presented in coherent ways, it's often disconnected and gets outdated very quickly. I can't speak as to the performance of the drivers (in general using the database drivers or a gRPC/thrift equivalent should be better than REST), but I agree with the lack of SLAs.

The lack of SLAs in the documentation is one of the major issues we've had when assessing the suitability of Azure managed services (e.g. Postgres, Cosmos DB, Bus, Event Hubs, etc.). To Azure's defence (not sure I should be doing this), a lot of these services are new and they are made available before they are operationally ready. For example, I was looking at the SQL warehouse offering a few months back [0] and if you want to use it you'd have manually maintain the statistics of the DB to keep the query plans optimised. It just seems like more overhead than necessary.
