As a Wii owner since launch, and someone that has seen the evolution of pointer controls for FPS games from the very beginning, I'm very qualified to tell you that pointer controls are faster, smoother and more accurate than dual analog controls. And this isn't an opinion but a cold hard fact.
As long as the customisation options are well designed once you customise your controls to find your sweet spot you won't want to use dual analog sticks ever again for an FPS game. They'll feel clunky in comparison.
I'm not entirely happy with the customisation options with MAG, they don't feel anywhere near as tight as the controls and customisation that has been commonplace on the Wii FPS games from The Conduit onwards. If Guerilla Games 'borrow' the control customisation options from The Conduit then the game will be fantastic.
