Agree, after researching this a little while ago, those are the two best alternatives. Was bit by HTTPie not supporting HTTP2, but both of those do. xh (Rust) is also faster (yes, in practice, try some large responses) than HTTPie (Python).

Edit: also just want to say, in a world where "the current GUI tool du-jour got bloated and this one has hidden behavior when you right click this button...", I much prefer command line tools where possible!
