I really like Svelte and have been using SvelteKit for more complex apps.

I've found it to be a great improvement over many cases where I would have used React before.

Svelte feels much easier to learn for someone who already knows the basics of web development, HTML, CSS, and JavaScript. But nowadays I often see people start learning web development by learning React, which feels a bit backwards.

Personally I have been using SvelteKit + Capacitor to build mobile apps, wrote about the setup here: https://bryanhogan.com/blog/web-to-app-sveltekit-capacitor

For simple landing pages I like to use Astro though.
