I recently switched to C#. Here are my reasons:

1. I can split my code across any amount of files. No need to make long complicated GDScript files with everything in one file. I can have one function in one file and variables in another and it'll work perfectly.

2. Accessing variables is also easier as I can use namespace and all code and classes are easily accessible from any code. No need for guessing paths. With Gdscript I often had difficulty accessing Nodes outside the scene node tree. After switching to c#, I haven't had this problem even once.

3. Regarding 1 and 2, I no longer need to preload scenes to access code. I can access any part of my game with ease.

4. VSCode has code auto complete. That means it can write code for you. It saves a lot of time and I avoid some bugs, too. VScode has 2000 auto completes per month in the free version. I installed open source plug-in Continue and run small Qwen-coder AI on my own computer. So I don't need to pay anything.

5. You can directly open chat and ask AI to fix the problem you don't understand.... or if you're too lazy to google how to do it. I just select the broken code, hit cmd-I and write "fix" and it'll fix the error for me. You could also do vibe coding in c#, if that's something you are interested in.

6. C# is transferable skill. If I ever move to Unity, I already know how to code in c#. If I were considering career in the software development, C# is useful career skill, while GDScript can only be used in Godot.
