Are you running the same applications and background processes? Is your WiFi signal strong, weak, wavering? Is your 3G signal strong, weak, or non-existent?

This would be nearly impossible to track every single element and keep them constant to do accurate testing of WiFi vs 3G. Realistically, use WiFi if you know you are in an area with good, strong WiFi connection or if you are in an area with poor 3G coverage. Otherwise, disable the WiFi radio so it is not scanning for networks and whatnot (even if it does disable when the screen goes into standby you do not want it searching for networks every time you wake your device).
those are the variables that are throwing me off. im just gonna go for the win and assume one radio (3G) wastes less power then 2 radions (wifi and 3G)
