Really love being able to reason about a globally replicated DB as if it was in a single location with strongly consistent reads. The mental model is so much simpler than a single-primary read replica setup.

The cost in write latency is worth it IMO since it's still usually fast enough for most use cases, and nudges me towards using alternative replication strategies for use cases that are sensitive to write latency (instead of deluding myself into believing my app is fast for everybody when it's only fast for me because I chose a primary that's physically close to where I live).
