I still say the composite body pedals are the best bang for the buck. I have the eariler generation of these:

They are light, cheap and have decent grip. I imagine the updated version ive shown here have even better grip. They take a beating, and you dont feel as bad about beating these guys up as you do a $200 set of something more bling.
They are also available from Deity, NRG etc….
My wife and I are using similar sets on our fat bikes (FireEye Hot Candy):
