I prefer VS Code myself. It’s a modern and fully-featured editor that is actively supported and has good AHK extensions.

I have to admit, I also use VSCode. FYI, @RaptorX has a configuration setup tool that works like a charm. The set up tool is not free, but it's not expensive either. https://www.the-automator.com/downloads/vs-configure-tool/
