Is it better to watch The Martian in 2D or 3D?

3D is usually the choice for me, unless others have told me it is distracting. However, 3D can be cause headaches, vertigo, and nausea for some people, especially those with neurological or vision issues. I attended The Martian with such a person, and for that reason saw the 2D, and found the plot, acting, and visuals excellent.
