In essence, you may want Hasura/GraphQL if you have no idea how the end-users' query format will look, whereas Cube is well-suited for providing performant results for somewhat predictable sets of queries. Disclaimer: I work on Cube.

My colleague Igor explains it better: Hasura is for CRUD with reasonable performance, Cube is for fetching analytical (quantitative) data with sub-second latency and high concurrency. Hasura is great as a general-purpose data backend, Cube is great as an API for analytics. Obviously, they can be used in the same app, e.g., a blog can serve posts and comments from Hasura and show an upvotes/downvotes chart or a rating of most productive commenters via Cube.
