Chess, fwiw, I spoke with a Behr representative about two years ago(take this anyway you like as a result), and he told me that Behr did a "blind" test against the major paint brands including names like Benjamin Moore and Sherwin Williams and many others where they allowed contractors who specifically favoured certain name brands to use paint out of unmarked cans on their jobs. I believe he said there were 8 competitors in total and Behr was favoured by over 50% of the contractors leaving 7 others with the rest much to the painters surprise.
Personally, I like Behr paint, it covers better than any other paint I've tried, goes on easy, has a rich pigment(?) and doesn't cost a whole lot. I've tried CIL a few times and find it doesn't cover well by comparison, almost seems watery and you need up to 3 coats imo. Benjamin Moore is good, but I find it no better than Behr despite it's higher cost. I've tried a couple of others, but I prefer the Behr both for quality and price.
