because Maya is better , and you know that too... the things you could do in max you could do in maya but maya gives the user more control than you could ever get in max. most of the users of maya don't know this but you could go in and edit and change all the tools and make them work the way you want them to, you could change Maya completly if you wnated and could... but you cannot do that with max. when working with complex lighting setups and shaders i could just make a script or an expression that could create and entrie light setup with one click, and change everything in the shot with another click....you could use scripts in max but not as simple as in maya.. and expression in max are not even close to expressions in maya...
i love MAX, i own max, but MAYA is my god...
Maya 7 rules... as my friend say maya is not for kids.. if you want easy use someting else.... if you want to play with the gods maya is you key...
