We've used Valspar v500 in several rooms and really happy with the quality. So far the rooms have been bedrooms etc, we are doing our hallway and will be using Valspar again. Is it worth us paying more for the v700 as it'll be in a "busier" area and likely to get dirty? It'll be a light colour too. Or is v500 ok? It says "easy to clean and maintain" but v700 says "most scrubbable".
