I whole heartedley agree with Steve. I only use Kelly Moore paint. I like the way it glides on for me. Tried the Behr once ( a quart ) didn't like it. Took the Behr to Kelly Moore for a color match and the color guy there matched it perfectly for me, in the paint texture I like.
Technique when rolling out the walls makes all the difference. Don't try to do to much at one time. As a side note I just completed painting my living room/dining room tonight for only the 2nd time in 8 yrs and only because I wanted some new color. I attribute the longevity to Kelly Moore paint.
