We switched to CockroachDB for some of our most heavily loaded tables a few years ago - and the scalability and operational simplicity has been great.

I don’t have a like for like benchmark, but at least for writes - we’re running with 5 replicas of each range so that’s 5x the disk write i/o just from that.

Add in some network overhead and running raft etc, and you are going to be needing a lot more resources than for PG to maintain a similar throughput - but adding resources when you can scale horizontally is so much easier that the tradeoff is worth it in my experience.
