Ric: (1) no-not at all (2) this may be the most asked question on this site; it is up to you to decide and only you-they are both excellent brands. Which feels more comfortable in your hands? Does one have a feature that you value highly that the others don't have? One isn't 'better' than the other but one may suit your needs more completely than the other-it is a personal choice.
P.S. I am a long time Nikon shooter-first film and now digital-and I wouldn't hesitate to recommend either brand to anyone.
Happy shooting! cb :-)
