I don't know. I'm not very familiar with Next.js (I'd heard about it but never really looked into it much). Your response inspired me to investigate, and I found an article by a Remix founder about the differences [1]. It's obviously biased, but maybe still interesting. It looks like there was an HN submission and a bit of discussion, too.
There's a bunch of other comparisons out there, too.
