I'm curious as well. My understanding is one notable differencse, exemplified here, is that Slint can work on embedded devices / no-std.
Most of the Rust GUI frameworks will run on something like a Kindle with 100's of MBs of RAM. Slint is the main one that will go smaller than that (it will run on actual MCU if you need it to).
