What is the best skin care line?

I have a mix of brands I like, but I do have a couple of products I use regularly. I use L'Oreal Revitalift day cream and night cream every day, and a couple of times a week I use St. Ives Timeless Skin scrub. These products combined help keep my oily, acne-prone skin relatively clear.
 
Before , I used La mer and now have been switching to La prairie white caviar illuminating for a year . And couldn't be happier. Also using Guerlain super aqua toner.
