hard choice tbh, haven't played a monk myself and DK is my main.
From what I see monks are very strong with lots of survivability (alot more than a DK) they also have decent burst + the 10% insta death move ;P
Dks on the other hand (esp frost) have insane burst on demand and ofc the ever usefull double deathgrip

Still unsure which one I would choose now though if I started new
