Twin Turbo has a nice ring to it, but twice as many parts...moving parts, at that (wastegate actuation, turbine spinning, etc).  More potential, too. 

But supercharging is popular amongst the VQ35DE contingent.  It'd be cool to have a shootout in the pages of Turbo, e.g., take the best turbo kit (under a preset price) and the best supercharger kit and test them back to back.
