I've fallen in love with the language since around last year, and I'm very active on the Discord server (the language is still in development so you can go there and give ideas, suggestions or just hang out!).
The stack makes it feel completely different from the other array languages. Instead of using infix functions with reusable variables, code runs RTL (for various reasons https://www.uiua.org/docs/rtl) and you can manipulate the stack with the various primitives, which I find nicer than the other array languages (APL, J, BQN, etc...).
Once you get a hang of the glyphs and their meanings you can really start writing code, which turns out to be very readable due to the colors the language gives to glyphs and user-defined functions, as well as the simplicity of how the stack works and how the language is designed overall.
