Vue is not a modeler. It is landscape/foliage 'environment builder'. It does some other stuff; but that is by far it's strongest area. It's a pretty good renderer too. Great environment builder.

C4D is 'full featured' 3d application. It has all of Hexagon's functionality, in general; and can do many things that Hexagon is not designed to do.

I don't use Hexagon; but have been told that it is a good modeler.

There is a good Vue -> C4D workflow. Vue xStream integrates well into quite a few other applications. C4D is one of them.
I'm not saying it's entirely impossible to build a Vue environment in C4D alone; but it would be damn hard and take FOREVER to do it.

EDIT - You could well find that you prefer making models with Hexagon; but still want C4D for all of the other things that it can do that Hexagon never was meant to.
