Modelling: Maya or Blender
Alot of people say it's the designer/artist that delivers better and not the software. Although that's not completely wrong, it's still somewhat wrong. Look at it this way, no matter how good we get, we always want something that makes the job Easier, quicker or more interesting. Working with Maya or Blender, you can get the exact same results (if you're that good) but you can also get the exact same results if you're that bad. Alright, time to differentiate them.
