Or any of the faster typed languages you are most comfortable with, as you might need to look at the code some times. LLMs are great at writing and understanding C# and Java.
The great thing about LLM-assisted coding is that an experienced software engineer can acquire decent familiarity with a language quite quickly. And then has a useful sparring partner for understanding and using the quirks and features of a new language.
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.
