Don't you find that although the ZWave mesh network spec seems to be more sophisticated that the Zigbee mesh network spec, don't you find that zwave devices (light switches, outlets, sensors, etc.) all tend to respond MUCH slower than a corresponding Zigbee device?
As I have stated previously, I honestly do believe that Zwave is far superior (technically). Better range, more error correction, greater interconnectability, greater penetration power, etc.
I also have to state that there appears to be a much greater consumer selection of Zwave devices in some key categories (e.g. switches, outlets, ...)
