If I learn the new verb c, which deletes and puts me in insert mode, I already know that I can type c3w to change 3 words, or ci" to change the phrase inside quotation marks.
Because all verbs work on the same set of nouns and adjectives I can intuitively know what many commands do - even though I've never tried them - as long as I understand the parts that make up the command.
I think the steep learning curve comes from the need to learn a richer and more precise way of editing, while you may be used to get by with a sloppy one. I had a similar experience when I switched to the Dvorak keyboard: I learned for the first time how to touch-type, while the Qwerty grew on me from hunt-and-peck.
Since you are considering about going back, here are some useful custom mappings of mine: - swap p and P; - map Space as PageDown; - map Shift + Space as PageUp; The last two mirror the way most document-displaying applications work. Generally, don't think twice about remapping some commands either to correct historical quirks of Vim or make it behave consistently with other applications you may be using, hence lowering your memory load.
Have fun
A lot of people here have made the point that vim has a steep learning curve that eventually pays off, which, to me implies that intuitiveness is either lacking or besides the point. Still, I agree with your other points. I'm thinking of going back to it to minimize hand strain.
