I don't think that there's a huge difference between the two. I purchased the B-Mobile because I had seen a video with a lot of successful hunts so I ordered a set. I also like to idea that you can buy an extra fan holder and use it as a jake or a gobbler. I've never seen the pretty boy up close so I can't comment on it. But I can set She-mobile inside of B-Mobile and roll them both up and put them in my vest but prefer to but them in the mesh bag that came with it.

God Bless,
