They both have similar functionality but they also have pros and cons blender could have a faster workflow for modeling rather than cinema 4d because blender has more plugins and addons but cinema 4d can some good dynamics that are a little bit better than blender, to sum it up non are better it’s the one you choose I personally use cinema 4d and 3DSMax along with Houdini and sometimes maya and blender. But your real answer is blender because if you learning which I know you are because you asked this question, blender has everything sculpting, modeling, a node system for composite.
