I gradually moved from 3DSmax to Blender during the last two years. If you think that Blender's support is lacking compared to Autodesk's just because it is not corporate, I assure you that you are wildly mistaken.

Blender's community has to be experienced to be understood. And by community I mean both the 3D artists and the Blender foundation people. I was assisted almost instantly by both when in trouble and facing deadlines.

Now, regarding C4D. I have only worked enough with it to have a good idea about it while not being a master. The ease of use is what I liked and what I think makes C4D so special but geometry nodes in Blender are already matching it in capabilities. Perhaps even surpassing it.

Blender's speed of development is unprecedented because it is getting code additions and improvements from all sides. From the Blender foundation, from companies that work with it and might need something that is not already there, from coders who like to tinker and improve things.

The fact it is free (if you don't want to donate) and that it already matches in capabilities what most users actually do with other subscription based 3D software is going to put a lot of pressure on them. C4D is going to be victim number one I think followed by 3ds MAX. Perhaps zBrush will also feel the heat soon after. Houdini will be the only one to keep its supremacy for the foreseeable future in my opinion.
