Rocket/Actix/Axum are all similar enough; I've used them all and I find Rocket the most ergonomic for web apps, Actix for pure backend APIs. I have spent less time working in Axum since it is the newest, but I don't have anything "bad" to say about it.

I started with Rocket for Notado, but because there was a long period of pre v0.5 stagnation, I went with Actix for Kullish. These days I'd be happy starting a new project with either.

As for Tera over Askama, I don't think Askama was around when I started building Notado; Tera was the first templating engine I used in Rust and I learned its ins and outs pretty well, so now it's just the default thing that I reach for whenever I'm building a web app.
