Regarding
http://jbenchmark.com/result.jsp it looks like that ROKR E2 is the fastest motorola phone. Second place (very close) is E6 (normal, since the processor and HW is almost equal). They are followed by E680, A910 and A1200. The rest are below 200 points, which nowadays is very poor speed.
What makes me little sad is that Moto do not have real top-end phone, which can compare with the Nokia and SE models.
Also it looks like that E2/E6 are very good competitors (the best CPU from all phones in the world, even not overclocked), but the lack of graphics card inside reduce their score in 2D and especially 3D rendering significant
P.S. Still waiting for Z6 and RAZR2 (V9) results
