Reason is simple that a monk has a more stable resource pool than a DH does. DH is very binary. You are either full or you are starving for Hatred. Discipline is not as bad but there are dry periods as well.
DH's deal very well in situations where you can plow through enemies fast enough to get consistent health orbs (passive restores a good chunk of hatred when you eat an orb) that keep up your killing spree. Higher difficulty and you'll blow your pool then spend 5-15 seconds darting around and kiting to build up again for another 10 seconds or so of hatred spending. Additionally DH's don't have a high amount of burst unless you have really good gear. When you have hatred you'll do competitive damage, but the down time to build up hatred will leave you doing about 1/3 of your potential dps.
Monks are very much like a freight train, you get them going and it takes alot of effort to stop them. The play style is very measured though. You Start off and build up a small amount of Spirit to use a spender about once very 10 seconds, as your rotation gets going you'll up that to a spender every 8ish seconds, once you're fully into it and have plenty of stuff to kill around you, or accessible packs within 10 seconds apart so you don't lose momentum, you can start spending Spirit nearly at will and never have dry periods. For me burst doesn't appear as high as a the DH but sustained dps is about 60+% of your potential burst as well.
