dvorak dates back to mechanical typewriters. it was designed to optimise alternating hands whilst typing, which made a lot of sense with a big, clunky key to push down, but isn't so significant for a new-fangled electrical button.
colemak's design was heavily influenced by a desire to keep certain common keyboard shortcuts in the same place to aid with some of those muscle-memory instincts, particularly ctrl+(z/x/c/v/a) and a bit of q & w as well, although i think those latter 2 are partially unmoved as they were already in a fairly appropriate place. This goal isn't all that important with a textblade with its fancy layering & OS awareness giving a standardised approach. Either as a secondary goal, or just coincidence (i'm not sure which) rather than alternating hands, colemak has a tendency to favour what are referred to as rolls, where you type a few keys in sequence with different fingers of the same hand.
both layouts (and the other, lesser-known improved layouts, of which there are many) encourage staying on the home row and/or stronger fingers for common keys. This quickly feels natural and pleasing. when i started to learn colemak the typing tutor i used had me typing real words with only 2 fingers on each hand, compared to the... far less useful letter combinations that qwerty allows i'd recommend giving one of them a go.
with the fancy jump abilities that the textblade provides, allowing you to leave the computer in your standard qwerty layout for other boards, whilst the blade translates into qwerty it makes it very easy to swap back and forth if you [need to quickly get some work done whilst learning the transistion / want to let a co-worker, friend, family, or whatever] use your computer.
whilst i touch-type in colemak, i do like to have my keys labelled correctly, for those times when you're 1-handedly trying to do a shortcut key combo, or slowly double-check why that password you just typed was wrong. So sticking to a layout that waytools offer keycaps for is a good idea imho.
