The Colab dry shampoos are indeed as invisible as advertised while Batiste can give a powdery grey finish if I use a lot. Half the lure of the Colab version seems to be the scents. Rio is fruity with papaya, pineapple and heart of cassis, while London is deeper with bergamot, musk and magnolia. I prefer London but neither scents last more than 3 hours and scent is not a major selling point for me when it comes to hair care.
While portable, where the Colab shampoos fall flat (pun intended) is their lack of volumization. They soak up some of my oil but not as strongly as Baptiste and after brushing, my hair is still flat looking. Even though they don't leave anything on my hair, I prefer the results from Baptiste more. It absorbs oil better and gives my hair a bit of a fresh bounce.
