Those are absolutely suitable. Blender is/should be capable of doing any of the UV map layouts and being able to make a texture template so you can export. I didn’t really do anything other than that. Going through and marking the pieces for color coding to know what is where on the UV map was what took the longest.
I’m not really familiar with Rhino aside from knowing about. I’ve never really looked the program. Zbrush is great but it it been a steep learning curve for me. I started with Mudbox in school. While Max and Maya both have a large amount of feature sets the basics of modeling can still be achieved in Blender. Using some of the modifiers in Max can help me achieve a look faster. This is something I’m not sure if it’s possible in Blender or not. I’ve not got a lot of experience with it. I’m slowly picking up some things here and there with it since it is a big part of the community here!
