I've gone very recently through a rewrite from Rocket to Axum and very much love it so far.

The initial motivation was the need for web socket support, which Rocket doesn't have (yet). But I love how simple it is, and also that it does not want to be the entry point of the application. (I like an http server that's a library that can be embedded at any place in the application.) Another great thing is the examples/ directory in the Axum repository.

I had to use the latest version from GitHub though to get some of the features I needed, but maybe that's not the case anymore.
