I never understood the logic of not using something because it's difficult to switch away from it.
If I need to program, I just copy my Emacs configuration to that machine. I have never encountered a situation where I'm forced to use stock Emacs, or someone else's Emacs configuration. If I need to make a quick edit from the CLI, using plain Vim is fine, but I feel more "at home" with my own tweaks. None of these things are hurdles that would make me settle for an editor that someone else has preconfigured for me.
At the end of the day, this will depend on how important you find customizing your working environment to your liking. If you're fine with someone else making that decision for you, you'd probably find the stock configuration, or someone else's configuration, acceptable. If OTOH you have strong opinions about the way you want to use your editor, then the time and effort invested in configuring it and managing that configuration is not an issue.
This goes beyond just text editors, and applies to computing in general. Some people are fine with using stock software as it comes from the manufacturer. Most software, in fact, is not deeply configurable. Apple devices and software are wildly popular despite lacking configuration. But the reason we choose operating systems like Linux, and text editors like Vim and Emacs is precisely because they give us the freedom to use our computers in the way we want to use them, not as someone else thinks we ought to.
