Duration consistently receives high marks. I like the color of BM's Van Deusen.
From ConsumerSearch:
Sherwin-Williams Duration exterior paint is very durable and retains a quality finish after the equivalent of nine years of simulated weathering in one independent lab test. The same test concludes that it does a good job of resisting cracks and color change, and experienced owners agree. Duration earns high marks from user reviews at Sherwin-Williams.com, where most laud its ability to withstand weathering over the years; many say it still looks great after five- and even nine-year periods. The biggest caveat we spotted is that Duration doesn't resist mildew and dirt as well as some other brands. Its premium price tag is a concern to some, but most experienced painters say it's worth it and that you'll spend twice as much in the long run if using a cheaper paint. Duration includes a lifetime warranty in case of peeling or blistering (not caused by improper application), though this doesn't cover labor costs.
