I dont know, I like Max a lot as well. Its polygon modeling toolset seemse more interactive that Maya's, and its subdivision handling algorithm is nicer then Maya's, though Max doesn't have the two subdivision creasing tools that Maya does.

Max is nice. I'm also learning XSI now, or going to start, once my uncle decides to let me borrow his copy. I think its good to start early if I want a carrer in the industry.
