95% of the time I am using the keyboard for playing quests. It's also the only thing I willingly use KB for as I use a controller for literally everything else, if I can (except the rare FPS, I tend to use KBM for those but I don't play them super often.)
Now If I'm playing a quest that has a lot of jumping, or makes use of basically all the buttons I will use a controller. I feel moving Link is still better with arrow keys, but I will forget what key is what sometimes since quests just have "A" and "B" and most people seem to use Z and X or some other combination. It's easier for me to on the fly read buttons as they would be on a controller face. Also some keyboards don't play nice if you are holding down two or more keys with an arrow key.
(voted KBM btw)
