Even when Emacs had two GUI versions, the default keys were pretty much the same between them, as far as I recall, excepting features missing from one or the other. For a very long time now, it's all been reconciled as GNU Emacs, anyhow, whether CLI or XWin GUI, or even on a Mac or (shudder) MS Windows. I just use my local running Emacs, with my preferred configuration, to edit files anywhere, such as inside a running container on a remote server in AWS, so it's pretty consistent for me.
