There's 2 types of web pages. Websites and web apps. If you're building a web app, you're going to want a framework that isn't going to fall apart the second things start getting complicated.

Probably better for performance and SEO unless you want to spend 10x as long micro-optimizing your SSR. Point is, there's different use-cases.
