I have never tried B&A, so I cannot comment. I have used both Abba and gelee. I love gelee. It is my fav gel. I like the way it feels putting it on my hair (slippery) and get decent hold. I don't think it is as temperamental about the amount that you put on your hair, whereas the Abba is. One thing to consider is that gelee was reformulated recently. I have not tried it recently, but some people don't like it as well as the old formulation. Sallys has a generic that some people really like (bioterra, I think). Abba is good for volume. It also has more hold IMO. If you use too much, you will not be happy with the result, so you have to experiment. Less is more with Abba.
