Is There a Renderer That Is Better for Beginners Than Others?

A lot of people like why you Cinema 4D is that learning curve was so low. I think physical actually is harder to learn than some third-party renderers. Arnold is probably a very easy one to learn. Redshift is a bit more difficult but more flexible in terms of it's got a very similar amount of controls in the render settings as physical does. But you'll be able to get there much faster.
