Same here, working with a team that knows Java, so I'm letting Claude write Java.

If I compare the results to another team that uses Python with Claude I see slightly better results on the Java side. Not because Claude knows that better, but because the tools are more rigid by default which creates more of a self correcting loop for Claude. The Python side has Pydantic, but it's a bit of an afterthought, while in Java you can't skip the type checking.

In the end you can do the same things on both sides, it's 95% a team/engineering culture difference. So pick the language that the team knows best.
