Henderson is nice. We looked there before buying in Summerlin. I liked the proximity to Red Rock Canyon and the mountains much better in Summerlin, as well as the lack of traffic (Henderson has more of a problem with traffic while the 215 loop in Summerlin helps a lot). But you can't go wrong with either location.
