I feel async is in a very good place now (apart from async trait :[ ) As a regular user who isn't developing libraries async is super simple to use. Your function is async = it must be .await and must be in an async runtime. Probably as simple and straightforward as possible. There are no super annoying anti-patterns to deal with.

The ecosystem being tokio centric is a little strange though

I love Rust and async Rust, but it's not true that there aren't annoying things to deal with. Anyone who's written async Rust enough has run into cancel-safety issues, the lack of async Drop and the interaction of async and traits. It's still very good, but there are some issues that don't feel very rust-y.
I've been writing async Rust for as long as it existed, and never ran into any cancel-safety issue. However, I also never used tokio's select macro.
I don't really appreciate the superlative here as I too have not run into cancel safety issues in practice.
