The interface and ease of use are what made me buy MoI.

Ten thousand Blender shortcut keys (which don't rhyme, regarding the keys, like Move is "g") are what made me NOT buy Plasticity.

AND: I need to model to exact specs, which is easy in MoI, but a pain in Plasticity.

Once Mike gets the filleting problem solved, there's no reason to even consider anything but MoI.
