Which is the better 3D modeling program, Adobe Photoshop CS5 or Blender?

I've been getting into 3d modeling with Blender recently, and I really like it, but I also have Photoshop CS5 and found out that it also has a 3D modeling portion to it. I can't find any information on how advanced Photoshop's modeling is, but was wondering if anyone with experience could help me decide which program to pursue so I don't spend my time learning a program when there is a better one out there.
