Sublime is an excellent editor and anyone who looks down on anyone else for their choice is not doing so because they are a Vim/Emacs user, it is because they are being an idiot.
Restating for emphasis. Text editors are tools. They're means, not ends. As long as you're getting your work done, I don't care whether you use vim, emacs, Sublime, Atom, VS Code, nano, or even notepad.exe.
At my last job, I used vim, one co-worker used emacs, while a third co-worker used Sublime. While we had our fair share of good-natured ribbing, I don't think any of us looked down on the others for using a different editor.
