What are the differences between Royal and Clark & Kensington paints?

What are the differences between Royal and Clark and Kensington paints is that both are Ace Hardware private label paints made by Benjamin Moore, but they are positioned at different quality and price tiers. Clark and Kensington is Ace's premium paint line, launched in 2011, positioned as top tier, costing 40 to 60 dollars per gallon, marketed as paint and primer in one with 100 percent acrylic, good hide, and available in flat, eggshell, semi-gloss, with over 1000 colors and better washability and durability, and it is often recommended by Consumer Reports as Best Buy. Royal is Ace's budget or value line, positioned below Clark and Kensington, costing 25 to 40 dollars per gallon, with more basic formulation, still 100 percent acrylic but with lower solids, less hide, requiring more coats for deep colors, and available in fewer sheens. Royal is marketed for large projects, rentals, garages, and where cost matters, while Clark and Kensington is marketed for living rooms, bedrooms, and areas where better finish desired. Both are made by Benjamin Moore, but Clark and Kensington uses higher quality resins and pigments, provides better stain resistance and scrub resistance, and has lower odor. Ace Royal is comparable to Glidden, while Clark and Kensington is comparable to Behr Premium Plus. So difference is quality tier, price, and performance, with Clark and Kensington being better.
