Fusion 360, Nomad Sculpt, and Meshmixer are my favorite design tools

With Nomad Sculpt, I model the organic parts, in this case the skull of Cthulhu. It is quite easy to learn and has a fast, very dynamic workflow. The downside is that it does not have an editable timeline.

With Meshmixer, I only make small adjustments or tricks. In this case, the Pixel version is created in Meshmixer. It has a very good tool for repairing meshes or making them more detailed, but it can also be used to create a pixel-style finish. I also use it when I want to create a Voronoi.
A free Autodesk tool that, in my opinion, is very powerful, not very well known, and somewhat underrated. It is no longer being updated, but it is still a powerful tool and can still be downloaded.

Fusion 360, without a doubt, stands out for its parametric power and its editable timeline. For anyone who wants to design mechanical, useful, and strong parts, this is your program. It is very easy to learn once you understand the interface, which is also very visual and intuitive.
