Disclaimer: I am playing devil’s advocate. I do believe Vim makes me more efficient with some trade-off, YMMV.
We, as developers, spend a lot of our time on our text editor of choice. Choosing to use Vim, in my opinion, ultimately won't make a huge difference with any other editor. The majority of modern editors are more than capable to handle the task at hand and are much easier to get started with.
You want to use Vim? Sure. After you are vaguely familiar with it, you will dive deep into Vim's ecosystem and soon learn about the variety of flavors Vim comes in and the many ways to manage plugins and configuration. Suddenly need to code in Java? well darn, you'll need to expand your code completion, syntax highlighting, and add additional functions like compilation.
And after going through all of that, would you argue that you emerged out of it a stronger better developer? Or would you say it was all but a distraction and the time spent there could've been spent on coding and learning about other facets of programming?
I use Vim daily and I love it, but it's kind of difficult for me to recommend it because it truly is a time-sink. What the folks rave about is more about Vim-navigation and not Vim itself, and that is easily solved with Vim-mode, which is available in most editors.
So, what's your stance on the general push for vim?
