I prefer Immutables for code generation. Lombok tends to interfere with Eclipse' code evaluations (last time I used it, it kept interfering with searching for a generated method's usage in your code base) and tends to confuse me when trying to figure out if something's an actual method or a method that was injected into the AST during compilation.

Immutables has its own set of problems, but at least it uses the standard Annotation processor and has a clear separation of generated code and the interface you write.

Haven't used Java's new record's yet, so don't really know anything about that.
