Most synthetic brushes work well with both latex and solvent-based paints, but always check the manufacturer's recommendations on the brush. Usually, but not always. But, high quality or more expensive brushes do have distinct advantages over the cheaper ones. First of all, a high quality brush will finish the job more quickly. Also, a top-quality brush will have a tapered end, which means there are shorter bristles on the outside and longer bristles in the center.
Tapered bristles give the painter more control over where and how much paint goes onto the surface.
