I only use Blender for modeling. I am more comfortable uv mapping and texturing in 3D Coat especially since 3DC has a built in link for exchanging files & layers with Photoshop. Since I am more of a photographer, I am very comfortable in Photoshop.

I also much prefer 3DC's PBR shaders over DAZ Studio's IRAY or anything Blender has to offer. I also use e-onsoftware's Vue and much prefer 3DC over Vue's materials as well.

I use MOI3D for the same type of models that many Blender modelers go to addons Hardops & Box cutter or Fluent to produce. I have Fluent but find MOI3D much easier and a lot more straight forward.

I do think MOI3D has a place in my car modeling, perhaps not for car bodies but it appears ideal for creating car frames, wheels, tires, engines, car differentials, etc.

My initial reason to get into 3D modeling over 20 years ago was to produce assets to be used in my Vue (e-onsoftware) renders and later DAZ Studio.
