Tough question. Modeling. Nothing really. A few tools that SI lacks like preserve uvs, lock sub components, sculpt tool, some tools that work better, but nothing special.
Animation. Nothing either. nCloth, nHair, and muscles may be an strength point but I almost never use them so I can't talk about it. Viewport. Even the old Maya viewport is better than the newest SI one. And this is a big difference when you have to deal with alpha bitmaps, vertex colors and normal maps when you're modeling game assets. Coding. You have access to a lot more places than with SI. But writing in Mel is a nightmare if you write something big, and the Python experience isn't very pleasant but I don't have experience with Pymel. ASCII format. Ignore version option. You can open data in older versions, sometimes. I find this feature a little unreliable since 2012 (or 2013?, can't remember) I can't think about any other big strength, sorry. Oh wait. It isn't dead, and you can find a lot of jobs and users around the world. It isn't a Maya feature but that's the main reason why Maya is the leader. Martin Sent from my iPhone
