Disclaimer: I haven’t used Exposed & I am the author of Falkon
Some things that Falkon does better:
- Android SQLite support
- Context aware fluent builders (insert, update, delete & query)
- RxJava (right now v1 is supported. support for v2 will be added in the near future)
Some things that works in favor of Exposed:
- Been around for longer
- More contributors (more eyeballs => probability for less bugs)
