I enjoyed the brief period I spent playing with Svelte. I ran into some bugs with the built-in animation support when changing states (there's built in animation support for changing states!) that I couldn't resolve, and which were pretty glaring in the UI. This was 6-9 months ago, though, so it may well have been fixed by now.

I'd really encourage all front-end devs to take Svelte for a spin, if for no other reason than to see a framework really trying to do things differently. There are a lot of nice ideas in there, and the works-out-of-the-box level is admirable.
