Here's my result with years of off and on toying around with 3d software.
none of the software really matters unless you have some artistic skill or can visualize what you want =) Much like programming, certain programs will be better than others at certain things. when you learn the syntax/interface of the particular tool, it will just become another trick in your batbelt.
Blender is a great program, especially for being free/open source. If you are starting early art classes, go ahead and try to learn it in parallel with other software. Sure you might not progress as fast, but it is full featured compared to the free offerings of the commercial software (ie, no watermarks, i'm not sure what the limitation of gmax is).
After years of hammering away at 3d, i've finally accepted i'm not creative enough in the artistic sense to take advantage of the software. I guess i'll stick with chemical engineering, hehe.
