Not really comparable to Blender: Wings3D cannot animate. Part of Blender's draw (pardon the pun) is its physics engine and animation suite. I cannot say for certain, but I suspect Blender's Cycles Rendering Engine is vastly superior to Wings' renderer.
We were discussing 3d modellers, and in that area, Wings3D is excellent. It only does a small set of things, but it does them very, very well. You can then import those models and UV maps into blender easily.
I absolutely love wings3d. It's the only 3d modeling app I've been able to create really cool shit with. I just love the vertex, line, polygon, polyhedron operations. It really lets you just kinda sculpt stuff and perform mathematical transformations effortlessly.
Super simple interface, and it's even written in Erlang.
