@T5115: It's not a matter of range or speed. You choose the 1 appropriate to the capability of your wireless devices:
If all your devices are capable of 'N' or better, as most modern devices are, choose 'N'.
If some of your older devices can only do 'G' or 'B', choose 'B+G+N'.
If you don't want to think about it too hard, choose 'B+G+N'.
