Is Blender good for 2D animation

I am currently using Cartoon Animator 4 and / or MOHO Pro 13 when creating my 2d animations. The Grease Pencil in Blender will allow me to create 2d animations in a 3d space, which sounds and looks great. The main questions I have for myself with this are, what is the time cost of learning and using this feature and are the end results going to be worth it? I suppose there is only one way to find out and that requires me to just dive in and start learning.
