Personally, what I'm looking for from an ORM is composability and type safety. To my knowledge, it's impossible with sqlx, for e.g., to conditionally add a WHERE clause, and have compile time checked queries. With diesel, it is possible.

I 100% agree with your point about Diesel's dev experience leaving a lot to be desired when it comes to docs and ease-of-learning though. But to me, that is a straightforward problem to solve when compared to the fundamental limitation of sqlx that I described above.
