"When renovating prior to moving we used a number of paints/primers during the process.
We started by trying to save money, and bought Behr ceiling paint from HD, what a mistake, looked less than great after multiple coats! We ended up putting a single coat of Flat, Extra White, SuperPaint over it, and it looks SO much better. There is also a High Reflective White base that is brighter, that one of the painters I talked with recommended, but I stuck with the Extra White since I thought it might better hide imperfections (Extra White looks white by itself, although when you put it directly beside the High Reflective White, it does appear slightly off-white/gray).
We used SW Balanced Beige 7037, Satin, SuperPaint for the walls. One good thick coat was almost sufficient, although there were a couple thin spots where I could see speckles of the previous yellow showing through...I had planned to do 2 coats, so it wasn't an issue. If the 2 colors were more similar, I probably could have gotten away with one good coat.
When I originally bought the SuperPaint, flat, satin, and semi-gloss were the only options, so I went with flat for the white ceilings and satin for the colored walls. About 6 months later, they came out with a "Velvet" sheen between flat and satin. Wish that was available when I bought the paint, since I hate flat because it is unforgiving with marks, but I also don't like a lot of shine (although the satin isn't too bad).
Summary: I would buy this paint, again, in a heart beat. Seems to be relatively good at hiding minor flaws."
