The BB Cream is quite nice, and has a great moisturizing texture. However, I personally preferred the texture and coverage of the CC cream by Smashbox. It feels like the texture is a bit lighter while keeping a good, natural looking coverage. The difference the brand promotes in the CC cream is mainly its ability to fade dark spots, sun spots, and acne scars over time (not just covering them)!
So I guess my recommendation would be to play with each tester and see which texture/finish you prefer! But in the end I'm sure you'll be happy with either!
