I'm not sure about a single leading OpenJDk build. It may depend on your use case, and even then, I suspect that they're all pretty interchangeable unless you have some very niche need.
If you're doing anything on AWS, Amazon's Corretto is a good choice. Probably similar for Azure and Microsoft's offering.
If you're using JetBrains IDEs and don't mind waiting for the major release (11, 17, 21, etc.), then those aren't a bad choice either.
I've used Azul's Zulu plenty for my own projects. One thing they do different is to provide alternate builds for every JDK version with JavaFX packaged directly into the JVM.
It's pretty easy to pick and choose between them and manage multiple versions from multiple vendors simultaneously using SDKMAN.
