Astro is pretty nice too, I was going to write my blog with it but I liked the instant page transitions that NextJS provides out of the box for which I couldn't find a suitable solution in Astro.
I recently moved from Gatsby, which did that — and the transitions sure are instantaneous — to Astro, which outputs plain HTML pages. Each navigation is a request to the server. Yeah, they take a touch longer. But the response is tiny.
You could always `preload`?
I worry that Astro is adding too many features and trying to become Gatsby. No thanks!
