I started a side-project in SvelteKit a while ago, and so far I still like it a lot. When I saw what projects using it look like, it somehow just intuitively 'made sense' to me. For me it's also just the right amount of 'magic' so that it's still quite flexible, but takes care of the parts that would be tedious otherwise.

(I've never worked with Nuxt or Next though, so I can't directly compare them.)
