Well at least it's a good deal.

For modo vs blender, it's really hard to compare.
You need to find someone that really master Modo and Blender to have an unbiased comparaison.

As far as I know Blender still can't manage vertex normals info right, something really important when using objects from MoI.

You should try yourself (there is a 30 days demo available) and see if modo works for you.
