Not a 3A, but thought I'd post my thoughts...
I've never tried the B&A, but it's definitely next on my list from Curlmart!!
I love to use a small amount (pea sized or so) of Abba WG for the front/top/roots of my hair (along my scalp). I also love a bit of it mixed with just about any other gel for the rest of my hair. It gives me GREAT volume & hold
I like the Biolage Gelee, but I have to be careful, as it will weigh down my hair if I use too much. It tends to give me a producty feel/look when I use too much, too.
