@User Thanks! I have tried Svelte in a couple of small demos and I think it is pretty neat. It has a couple of philosophical/feature differences to Stencil imo but both share a goal in following web standards.
Stencil is a component compiler, meaning you can write a component once and output to custom HTML elements, React, Vue, Svelte, etc. This is a pretty great feature when you are building components that need to be consumed in a variety of contexts! (For clarity, I work on Ionic Framework which uses Stencil, so I am biased haha).

Also, my personal preference is jsx > Svelte's templating lang. But again that is just a personal preference, I am really excited to try out SvelteKit sometime
