I started my career programming in C for an embedded controller, but have since moved on to C#, which is by far my favourite.
I've also dabbled some in Python and a lot in Javascript, but I much prefer type-safe languages in general.
Python''s whitespace-oriented design also rubs me the wrong way.
C# has come a long way since I started using it, and it now being both OS- agnostic and well suited for backend services has made it my go-to for personal projects.
Frontend applications are still written in JS, however much that hurts me.
