Great to see actix-web reach 1.0. I've played with Rocket in the past and liked it, but ended up choosing actix-web recently for a production project because I don't want to rely on a nightly compiler for a production project. I'm only using actix-web in a small portion of a larger Rust project, but so far my experience with it has been quite pleasant.
First time I even tried to use Rocket, I couldn't get there Hello World thing compiled. I honestly don't know if it was my error or a nightly compiler incompatibility and that sucked.
