Vim user here. I find the weird arrow key arrangement works well for how I use vim.
I hardly ever use "h" and "l" to move around if ever, I'm usually jumping around a line by finding a character rather than holding down or hammering a letter to move my cursor toward a position. When I use "j" and "k" it's either to adjust my position after I jumped too far and more often to perform an action like deleting lines. I tend to use "j" way more than I use "k" in these instances.
I'm not sure if my brain adjusted to use "down" more often because "j" is under index finger or if "down" being under the index finger was a design choice by a keyboard manufacturer.
I hear to be a vim expert, you don't ever use hjkl at all

I got to get me some of those vi caps!
