Have you checked MeshFusion after they overhauled gui for it in 10.2? While previously it was a pain to use now it seems they are nailing it.

As for general usage of Modo - personally I found modeling in it quite easy, fast and enjoyable. It still IMO is one of its strongest points. But it is another story when you start digging outside modeling - usually it is as complex as most of the dcc apps out there. As they caught up with huge chunks of functionality I hope they'll work on workflows - hopefully new MeshFusion gui is a good indication that they're aware of the issues.
