I'm currently building a project using App Router. Here are my thoughts so far:

1. In React Server Components, you fetch data at the component level instead of route level. You can pass the data down as props if it's a client component.

2. I'm not sure if HMR is faster in Pages, but in App Router it tends to be slow. I always use --turbo to see changes quickly, but it can still be a bit buggy.

3. I just found out that using "use client" directive isn't actually sending 100% javascript to the client. It's just a replacement of serverSideProps. The component is rendered both on the server and the client, which can be confusing at first. You can disable SSR using dynamic imports.

4. I actually like Route Groups, best feature by far.
