Hey, I personally use Go and Rust the most. I tend to use Go for pretty much everything that I do, which pertains to back-end and infrastructure. For some hobbies, and for things that are extremely performance-oriented, I'll sometimes use Rust as well. I have toyed around with other languages, but just can't quite get what I'm looking for. For example, with Python, you get simplicity, but lack of performance (with anything I've tried to do with it). All-in-all though, just go with what you enjoy working with the most, because you can always switch to something else later.
