Advantages of async runtimes other than tokio?

In the interest of sparking a little discussion (not too spicy please, we're having a nice clean start here) I thought I would ask the question. It's something I'm legitimately wondering about as someone who has reached for tokio by default for years.

I'm aware of async-std and smol, probably unaware of others. If you've used or prefer a different async runtime, what trade-offs might I be interested in or what features am I missing out on?

Not so much relevant for production use cases but from an educational point of view: whorl is pretty great. One file that explains async runtime basics from top to bottom. The cleverness of doing this in one source code file is remarkable.
