Dvorak still has the alternating hands rhythm that Colemak lacks, being more built on one-handed finger rolls than Dvorak. Most people I speak to prefer the finger rolls of Colemak, but some people (like me) prefer the alternating hands rhythm of Dvorak.

(That said, I still use Colemak because it happens to work better for my native tongue. If I only wrote English, I would have been a Dvorak user.)

What I'm talking about is a UI/UX problem that cannot be solved by key layout, I even experimented with a Ergodox and ended up in keybind hell really quickly because supporting one application others very quickly.
