It’s worth mentioning Blender 2.8 too. This is software people are leaving top tier commercial 3D apps like Maya for because it is better. The stereotype of unfriendly UI and UX in open software is breaking down and does not have to be a given.
Blender is good for character animation, but it's learning curve is higher and there aren't as many QoL improvements as in other 3d software. 2.8 is a step in the right direction but I still find cinema4d to be much much much faster to get results with for my purposes of motion graphics.
Speed really is the crux of the biscuit. It's not like you can't get the same results using FOSS, but the amount of time and effort to do so is significantly increased.
