While I've never had the Chrome World Air Deflectors I have had the Honda brand air deflector which are basically the same shape and style.
I have to say the Baker Built smooth out the air flow better likely due to its shapes. I happen to like the way they looks and the SO does too. In my unofficial testing, the air seems to be moved out farther that with the Honda brand. The other thing I like is that the acrylic used seems to be more damage/scratch resistant - harder. The Honda brand is clear ~ after just a few years of use, it looks terrible, hazed and the chrome is peeling too.
Installing either can be a bit daunting for the average person since you have to either drill large holes for the Air Wings or cut into plastic trim strips for the Air Deflectors. It was an easy task for myself having aircraft structure repair and machinist experience ~ measure twice (or thrice), cut once.
I'd suggest just diving in and getting the Baker Built Hands Wings and Air Wings with lowers and be done with it. I was that impressed I ordered the Leg Wings too. In Alaska, riding can, at times, be cold, wet and gusty. I want my wife to be as comfortable as possible. If you are a solo rider, it is still a great upgrade that the driver benefits from as well.
