I've read 3ds max 9 (2006) documentation. It's the best software documentation I've read in all my life. It covers everything from basic to really advanced. I don't know how the documentation is today.

Less features? The only thing I can think of are the advanced topology surfaces that rhino has. I'd argue most people don't need or want those.

What I REALLY dislike about max is the subscription model. It encourages piracy in all but the wealthiest nations worldwide.

But the biggest downside of all is being windows only.
