The benefits pile up quickly when you want to do something even slightly more complicated. Hit w a bunch of times until the selection looks right, rather than count words. Tweak either end of the selection to catch spaces or punctuation.

You can do all this in Vim, I'm sure, but it's less mental effort in kak, because to a much greater extent you can see the results of your actions before they happen. And it's no slower if you do happen to know exactly what you're doing, because it's almost the same keystrokes in different order.
