Hey, blender is actually able to preform almost all the things maya or max can too. What exactly are you struggling with? Post it here, we have a huge community of blender users that are happy to help you out.
I cant quite point out advantages or disadvantages over maya/blender as I only work with maya tho.
But yeah, before you make and rash decisions like that, make sure you have tried more stuff before you give up, let us know what the issues are.
