Good backend framework for Nextjs

Hi devs, I've been using Next.js for almost three years, and while it's a great frontend framework with solid full-stack capabilities for small to mid-sized projects, it struggles with large-scale applications due to Node.js limitations.

Now, I want to deepen my backend knowledge to better handle large projects alongside Next.js. After researching, I found several options, including Spring Boot and NestJS. I understand they have different strengths, but I'm curious to know which one might be a better fit or offer specific advantages over the other.

Thank you in advance 🙏🏻🙏🏻
