I don't think the two are really comparable - completely different querying paradigms. Athena works by writing SQL queries against JSON, CSV, or other kinds of documents stored in S3. You pay per request and per GB scanned as part of your query.
MDB is a fully fledged database that can do aggregations, queries, etc.
I consider those two products addressing totally different problem sets but if you've found places where they're the same I'd be interested in learning more.
