Why would a competitor build this Riak benchmark? How are they supposed to know which Riak configuration performs best?
That's the point of YCSB. Each vendor can submit the optimal configuration for their system, and they all run the same benchmark.
At the end of the day, each vendor is going to publish benchmarks that show their system performing better than all others.
It's your job, not theirs, to verify those benchmarks for your particular work load.
Edit: Also, while Mongo wouldn't classify as a distributed store, Cassandra definitely would. In fact, it's more "distributed" than Riak, since you have to pay Basho for multiple DC support (unless that's in the open source version?), whereas Cassandra is completely free.
Have you looked at YCSB? It's a pathologically poorly designed benchmark. It essentially tests how good a developer is at implementing a Java wrapper around a toy object model and interfacing that with a database.
A proper benchmark would hold constant things which are reasonably expected to be constant: the use case scenario, the data, the warmup requirements, the concurrency, and the count. If feeling frisky, the hardware, operating system and networking environment. And then step back.
For example, "On an EC2 Extra Large instance running Ubuntu 11.10 with whatever tuning the package recommends, what is the transactions per second when 50 vendor-provided clients on the same LAN are attempting to write and read random records out of a pool of 10mm 5k records?"

If things haven't changed in the past year you are right about not being able to do replicated multiple DC support.
