I have looked at both for quite some time, and selected the JW Speaker Evo 2. LED lights are very directional, and many reviews talk about how they lose the light in front of them while cornering because as the bike leans, so does the light. This is a LED issue, not a brand issue. The JW Speaker Evolution 2 lights seem to have a small amount of additional "halo" light around the main light beam, which may help with light drop off problem. The original Evolution and the Phase 7 do not have this. Hope this helps.
