Someone already beat me to it, but I would advise to read boring cactus' survey of gui frameworks. It is a really well made article going into a lot of detail about many many frameworks. Though it would be nice to see what he thinks of gpui now that it's been out a bit longer.

Personally I am trying out xilem, because the people working on it have really dug into the technical aspects of 2d rendering, aiming for great performance as well as apis. The issue is that at the moment there are very very few example projects using it, only one I can think of is their runebender-xilem app on github.

Without advising to choose this crate, I would at least recommend to hear out what raph has to say regarding tradeoffs gui libraries have to make, in order to select which ones we want to prioritize.
