I was contemplating switching from Cinema4d to Blender for a long time, but the UX of C4d was so nice and Blender’s frankly sucked. Then 2.8 came out with a UI overhaul that changed all that and now I’d never dream of switching to another 3d package when Blender is so easy to use, extensible with Python, and has a huge community around it. Blender’s popularity soared after the UX changes. Sometimes, a UI overhaul can make all the difference.
Even where Blender falls short, there’s usually an addon that fills the gap, often paid, but still open source, which is 1000x better than competing options that almost always involve a subscription.
The benefit of a community of open source software around it also can’t be overstated. For instance, MakeHuman kicks ass, Auto-Rig Pro makes it usable for mocap and character animation, etc. Blender Studio’s projects like Flamenco render farm and automated Blender Studio pipeline built around the also open source Kitsu that I self-host are also amazing. Collectively, it all blows Autodesk out of the water and should be a shining example to all other open source projects.
I haven’t used Maya since the early 2000s when they had the Personal Learning Edition. I remember being put off by the 3 mouse button requirement and the weirdness of the UI at the time, but found C4D drastically more intuitive. Maybe the Maya UX has improved a lot since then, but I found Blender 2.8 slightly less intuitive than C4d when I first started, but not bad overall, compared to being completely put off by earlier versions of Blender’s UI as I had been with Maya. The expensive subscriptions for both Maya and C4D are definitely more off-putting than anything else, though.
