From the professional painters I've talked to, (and you know me! If I have a question I call people ) Pratt and Lambert is one of the best. They also mentioned Benjamin Moore and Pittsburg Paints, Martin Senior, then followed by Sherwin Williams. The commercial guys don't really use Behr, that's more for us home owners and people that like the faux finishes. Doesn't mean it's bad, just they don't typically use it.
