Dangerous to compare these by just looking at features or pricing. Based on my limited experience from these kind of shared services I would say the devil is in the details and in performance. In shared services one interesting topic is how the various limits are implemented. Is there some hard timeouts that prevent complex queries? Is there throttling? Do you get some kind of penalties for running queries that are not optimal? Do you need to implement some specific retry-logic?
