I absolutely want to learn VIM but saying it's only a weekend is plain misinformation. We're definitely looking at months of gradually building new habits.
Agree, and I would add that it's not just habits, it's committing to rearchitecting your workflow. Do you use things like debuggers, linters, refactoring tools, project management tools, etc.? Get ready to learn totally different tools (usually)!
I'm a committed (neo)vim user, but I readily admit I only got over the hump because I thought it was cool and hardcore and typing is easy for me. There's no question it's been worth it for me, and I would argue it's probably worth it for most people and better for the software ecosystem as a whole (GUI tools don't compose), but still I think trying to say one's better than the other is too narrow a view.
The basics are very simple. You just get used to formulate a (weird) sentence of what you want to do in your head, abbreviate it and then learn (or configure) the buttons.
The problem here is the "just" word. To you it's "just" (as in a day or two), to me it's "I have to learn to think in a new way and that will take a while".
