I think FoundationDb got great scores from Aphyr, sadly it is now owned by Apple. For the others the big problem is when they promise some kind of ACID and cannot achieve it, if they were explicit with what the supported all customers could make informed decisions. Relations systems are generally bad ad horizontal scaling and can get very slow with full ACID over many servers.

FoundationDB ran Jepsen internally and reported stuff[0], Kyle never worked with it.

Curious: how difficult is it to replicate aphyr's tests? Can we beleive independent entities posting jepsen reports on some random DB?

I think that's a false equivalence. Aphyr is pretty positive about Riak (with the correct configuration) and Cassandra (when used for appropriate scenarios). If I was choosing a new system those are the two I'd be looking at.

Antirez was very receptive http://antirez.com/news/55

Aphyr wasn't overly impressed by that response though https://aphyr.com/posts/287-asynchronous-replication-with-fa...
