I think it is a good idea to start off with the classic 6 pack just to get an idea/feel of the basics of flying. Then switch to the g1000. I know from my own personal experience I started in the g1000 for private and instrument. For commercial I went to a legacy 6 pack and actually liked it more. Both are great for learning, but in terms of practicality for the future, you are going to have avionics like the g1000 in front of you.
