I'd say that would be splitting hairs. But arewewebyet has downloads badges for the frameworks. If we go by those numbers, Iron has significant lead and Rocket coming second.
Also just for fun I did try out Iron, Actix-web, and Gotham, and they all put out pretty similar figures (iron&gotham bit smaller, actix-web bit bigger). I do feel like Rocket is being a good representative example here.
That being said, I wouldn't be surprised if Rocket would be bit more feature-packed than Jester.
Fair enough. I just know that the main complaint I see against Rocket here is that it requires nightly (and supposedly enough nightly features that it may be a while before it doesn't). As something that requires a developmental build of the compiler, it didn't seem like the best representative sample to me, but if it's about par with other frameworks, then it works well enough.
