I have moderate experience with paint. I suppose I do not understand why someone would not just use Glidden for the interior paint... I painted some dark, faux wood paneled rooms with a light blue glidden and I do not recall it being any harder to cover than my olive green living room was with a light creamy yellow Behr Marquee (custom, Lowes Cameo Homestead White color matched). It did not take one coat. It took two. But, that being said, it was easy to apply... has a very nice finish. I have nothing negative to say, I just don't think that Marquee paint is needed for interior. Now, for the exterior, I'd pay $100 a gallon if it were the one and only time I'd ever have to paint it!
Also, regarding that it took two coats, I think that was a combination of using a medium quality roller with a textured wall. But, if you read closely, Marquee says on the container that it does not stand by a one-coat coverage guarantee unless it is certain colors covering other combinations (it specifically states that Ultra Pure White will require more than one coat). So don't buy it just for it's one coat coverage. I would personally stick with Behr but get the Premium Ultra rather than the Marquee; I feel like I spent an extra $10 for no reason. I may try it out again though.
Very Adhesive, Even Application, Easy to Apply, Good Coverage, Easy to Use, Looks Great, Dries Quickly
