Well, Colemak is better than Dvorak, but it's not without flaws unfortunately. The biggest offender must be the placement of the H key... it's left on the same spot as on Qwerty, but as noted by the dude who designed Workman, that makes typing 'the', which you will type a LOT, a bit uneasy. You type t, reach for h with your right index finger, then hit e with your middle finger. But it's not easy to reach h without slightly moving the middle finger, which slows down the typing of 'the', and it's a pretty annoying movement to boot.
If this isn't a problem for you, then it's really Colemak all the way. But as for me, it's not pleasant at all. Out of Dvorak and Colemak, both are more cumbersome for my hands than the layout I designed, which I happily use.
Lastly, I wanna point out... this layout business isn't as complicated as that dumb article is making it out to be. Finding out if Dvorak or Colemak or whatever is better for you can be found out before learning it. Typing is just a matter of using your fingers to input stuff.
