You have to get get the Luxeon V just to experience it's tint and beam pattern. Even though the V is only 70% CRI, the way it picks up reds makes it feel like a higher CRI. I live in a forested area where browns dominate most of the landscape for some of the year. So that is very helpful for me. The Luxeon will be a bit floodier. Aside for that, it does have a lower Vf and better thermal performance. Here are two charts from djozz's testing. You need both to compare the V to the XPL.
