For just brushing/detangling wet (or dry too I imagine) hair, and not for styling, I bought one of those crazy gimmicky Tangle Teezer brushes and it's amazing. I have fine tangly hair and it just glides through and I never have to fight tangles.
For brushing dry hair to distribute oils or to get out loose hair before I shower I like wood bristle brushes because they don't pull at my hair, and my hair can get knotty with the wrong brush. Widu brushes are supposed to be good, but expensive. The one I have is made by I think Earth Therapeutics, the company that makes all sorts of lotions and foot scrubs and stuff like that, I got it cheap at Marshall's years ago.
If I detangle first with the Tangle Teezer I usually style with a classic Denman brush (this kind) http://www.folica.com/tools/hair-brushe ... MgodOxEAvw
It has plastic bristles but they don't have the stupid annoying nub on the tip (I hate the nubs, they always catch on my hair.
