Ability to use the debugger is one of my top priorities, I will often redesign an entire plan of it breaks the debugger (Either because it uses DSLs, or it's too strongly multi language, or it's not runnable locally on the desktop at all). Same for version control, linting, and formatting, I pretty much ignore technologies that don't integrate with all the modern dev tools most of us expect to have.
