Citadel vs. Databricks Internship

I've been lucky enough to get internship offers at Citadel and Databricks for the upcoming summer. Citadel definitely has a great name and exploring a different area (finance) could be cool, but Databricks seems to be growing really quickly and is a hot company right now.

Another factor I'm considering is I'm interning at Facebook again in the winter, so I'd be very open to trying something different this summer.

Would love your thoughts!
