I smiled when reading this post because I absolutely recognize the euphoria of carrying out a world-changing refactor and having it work first time. If this is what the future of backend development feels like, sign me up!
In comparison to rocket, actix-web does not use codegen tricks so is not as ergonomic or as safe - e.g. it cannot statically check that the path variables that you ask for actually exist on the route - but these are things that a simple test suite easily picks up (incidentally actix-web has a nice built-in test server).
Also I was a little concerned that rocket development has stalled somewhat. 26 PRs waiting at time of writing. As I recall the maintainer is teaching a Rust class as Stanford so he's most likely just very busy.

I only have minimal experience with it, since I've also eventually chosen actix-web for all my projects so far due to its simplicity.
