10 reasons why Blender is better than 3ds Max

1. It's free.
2. Upgrades are free.
3. Huge community
4. Lots of tutorials
5. Works on different OS (OS X, Linux, Windows)
6. Unlimited Render Nodes
7. Starts up much faster than 3ds max
8. Is more stable than 3ds max
9. Smaller footprint than 3ds Max (The installer is less than 100MB)
10. It has sculpting tools similar to zBrush and Mudbox, 3ds max does not...

I myself work in blender. But there are almost no jobs in Blender, this is a huge minus.
If you are an Indie Game developer blender is perfect. If you want to find a job as a 3d artist it is better to know a mainstream 3d software like 3ds max or Maya.
I hope this will change in the future.
