In my experience, spring has been intuitive until you need anything slightly custom, or until layers deep configuration / reflection magic bites you. Other thing I didn't like about spring was that documentation was pretty sparse and didn't explain concepts well, it's either some hyper-specific tutorials or reference docs. (There are some good blog posts though, but I couldn't build a comprehensive mental model just following the tutorials). It's still what I reach for when I need to spin up a CRUD API quickly. Rooting for quarkus to become more mature though. (Recently tried based on someone's recommendation on HN).
