Followup: I dug up some benchmarks. Probably the best quote:
"The unnamed data cloud platform consistently had the highest price-performance4, across a range
of 11.5x to 13.1x".

This was on the Berkeley AMPLab benchmark, and the link I followed mentions Snowflake -- there's apparently a bit of winking and nodding going on here about the "unnamed" data platform.
Basic query latency was also considerably longer for SF.
