For learning 3D I wouldn't have traded my Tuffflight 4D for anything. Over the last year or so I must have crashed/dorked my 4D over 100 times, and to this day it is still flying. I started to learn with a Morris the Knife and after the first crash (were I destroyed the airplane) I got very frustrated.

It is MUCH easier learning to hover down low close to the ground, and the 4D allowed me to do just that without the fear of picking up balsa pieces.

The 4D will increase your learning curve dramatically.
