Solo Shadowknight vs Monk- snare question

[Polixa]

From the numerous threads/articles I have read, it seems players generally consider soloing a monk to be easier/simpler/better than soloing a SK. Damage avoidance and DPS both being on the monk's side.

Not much is made of the SK's ability to snare - outside of fear-kiting. I am wondering how powerful a tool it becomes when soloing in a dungeon and preventing runners.

Is this ability enough to allow a SK to solo deeper in some of the L30-55 dungeons than a monk can, or is the ability not really enough to tip the scales in the SK/monk debate when it comes to solo tanking dungeon mobs?
