Very nice. I personally found it much more fun and stimulating to pickpocket mobs. Plus you get all the poison mats you will ever need. Also high level mobs can drop green gems from pickpocketing. I know, know it, it takes longer to pick pocket but it is a ton of fun and you never know what you will get.
I have received super health potions, noble topaz( and other green gems) , super mana portions, romance novels, cook books on how to cook humans, etc.
