While I wouldn't exactly put it in the Rails category, I love Spring Boot far more. I love Micronaut even MORE than Spring Boot... but that's another story.

Spring Boot doesn't tick ALL the Rails boxes (Scaffolding a backend CRUD admin interface, all of the complex templating stuff - although Thymeleaf is pretty darn good) I'd put my money on it being more maintainable a year later. Spring as an ecosystem is huge, so there's always a strong possibility someone else has already solved the problem you're trying to solve. The tooling is pretty fantastic as well. Kotlin as a language is just fantastic.
