Which form of animation is the best for a beginner?

I'm comparing 2d vs 3d today. Which is better in terms of "learnability" vs. Time, practicality, and user friendliness.

Which do you think is the fastest for an average artist in terms of making his own 3-5 min. Short, 2D or 3D. This avg. Artist has good drawing skills, and can learn well.

I want to produce, or create a story. But I want to be able to put it into film. There are many instances in where animation can reach versus traditional film, budget cuts like a space setting. Of course, hiring an animation team can also be an option.

To those who have done animation or 3D, or both… What advice can you give for someone who is wanting to create? And by create, I mean the usual 3-5 min. Film just to tell a story.

There are mod users, like Gary's Mod or even Minecraft in where artists animate shows WEEKLY, how do they do this alone or with a group of friends? I am curious to know…

Added (1). For 3D, why can't I just wear a green body suit against a green screen, do an action and just render it on a program with the mesh of my choice?
