Depends on your preferences. One advantage with starting with ODE scripts is they already have adapted to OpenSim[1]. Other than that, there is something to be learned from any of the scripts.
-- mb [1] Like, several SL vehicle scripts rely on a timer to set velocity and angle but OpenSim's default minimum timer interval is 0.5 seconds which is way too large for controlling vehicles.
