Obviously the Vue ecosystem is much larger but other than that, personally, I much prefer Svelte.

I used Vue 2 as my main framework for some years, and still maintain a couple of projects with it.

I'm now focused on Svelte. The performance is better, the bundle sizes are much smaller, and most importantly you write a fraction of the code to achieve the same thing.

Svelte also has a reactive primitive (they call them stores) which allows you to model pretty much anything with reactivity similar to what you'd do with MobX but with a fraction of the cost. I believe Vue 3 also has this now but uses Proxy which is not supported in older browsers.
