Clay, I have had all 3 and the best all around is the Pirahna, I haven't needed to take it off as you can still back drag to level, still scoop dirt and clean up the weeds. I modified the Ratchet Rake to fit my BX and if I am doing a major clean up I would give it a slight nod over the Pirahna as it works well both directions. The challenge is you have to take it off to dig. If you can have both go for it, if it is one then the Pirahna. I gave away my tooth bar as it had no value over the other 2. With I had the Pirahna first it would have saved me some $$. Good luck with a purchase.
