I have both for my B3200 but I think they are two different tools if you have larger trees and stumps the tooth bar works great but small saplings and briars the Rachel rake is the way to go. You wedge the pricker bushes in between the teeth and pop out the whole thing roots and all. I cleared a fire pit area back in the woods probably 50' by 40' it was full of prickers and poison ivy. Cleared all that with the RR and two years later nothing has grown back.
