I'm going to have to try the new Behr with primer - I've used Behr in the past and had good results, except with enamel for trim. And that could have been due to the prep (hubby !)
I really like Valspar Premium (Lowe's) I'm using it in our "renovation" and we love the results. We've done 4 rooms so far. I know people who won't use anything but Benj Moore or SW ... it really all comes down to the prep, quality brushes & your application
:)
