I like Sherwin-Williams products. I use their products. Good paint should help you achieve good results; it is easy to apply, has flow quality that helps smooth out your brush strokes, don't dry too fast or slow, and gives good coverage (I think they call it "hiding"). Sherwin-Williams products always help me get good results. Their paint looks great. I also have one of their sash/trim brushes and I remember that not one time did I wish for a better brush while I was using it.

Painting is such a big and time consuming task that you might as well get the best you can for the job. Having to re-work a paint job is painful.

Benjamin Moore is probably another good bet. I just haven't tried their products.
