Vertica is a pretty large commercial column store with a lot of customers. Although I'm not sure if the Yandex folks got permission to publish benchmarks about it...
(MonetDB is a classic research columnar database, and I believe MemSQL has a columnar mode. Greenplum is missing, for some reason.)
It looks like they benchmarked against MemSQL 3.2, which is nearly 2 years old and Hive .11, which is close to 3 years. Not sure how out of date the other comparisons are.
