I've used both systems extensively and I'm prefectly happy to use either. Both companies make great cameras and great lenses and neither system is going to get in your way or make you a better photographer. If you're inclined to buy Nikon, then Nikon is probably a good idea so that you don't have any buyer's remorse. Like I said, neither camera system is going to produce bad results so going with your heart is a fine way to buy
