IMO, the Judo guys have better "throwing resistance" and "counter throw" skill than the BJJ guys. In average, it's much harder to throw a Judo guy than to throw a BJJ guy.
Well considering the whole game plan of someone in BJJ is to get to the ground it's kinda null and void. I agree the manner of delivery is important (you don't want to land on your head or something) but most takedowns Ive seen from BJJ is an entanglement drag to the ground. That's why I think wrestling and BJJ together make a very good compliment to one another. wrestling has excellent takedowns and BJJ has excellent submissions.
