Quality of pointer aiming is pretty different between games. I only tried the Time Crisis demo, but it was really jittery. The only full game I played was Dead Space Extraction and as good as the Wii. I remember Giantbomb people saying House of the Dead felt better with Move than Wii, but I didn't have a problem with the Wii controls were normal, so I don't know what they meant.
The tech is pretty different the wii remote is a camera picking up the two signals from the sensor bar, while the Move is calculating everything. There is calibration, but on the bright side, you don't need to be aiming at the TV which can be more comfortable. Even if you block the camera it still works, only it cursor drifts more.
If you already have a Wii, I mean, most of the Move light gun games are already there, just uglier. plus there is a better selection with ghost squad and hotd 2+3.
