I don't know how people do it but I can't press 6-0 on the keyboard with their left hand without looking at the keyboard mid play. My KB set up usually ends up with 3 stacked bars going from 1-5 plus other around-wsad shortcuts. Still, that usually ends up making my left hand do all the work and left+right mouse hold to do precision running just doesn't feel right.

Plus, performing an uncommon set of actions (combat actions done in an order you dont usually do because a certain fight requires you to) feels better on controller because each of the actions have a distinct way of activating them, especially when they're on different sets. Then hand motions you do for everything on your kb hotbar are largely the same. Some may argue that it's better that way because it's faster but I prefer the former and my hands are fast enough for it.
