They are a little different. You can decide if the difference justifies the cost.
The nybarbell has more whip to it, the Elite is thicker and stiffer.
The angle of the of the yoke is different, although I don't feel any difference from that in the lift.
The yoke itself is different, the pads on the elite bar are much thicker and harder. The nybarbell feel they would probably need to be replaced much sooner.
All that said, I bought the nybarbell with my money (well my wife bought it for me as a gift). I have a buddy who had the elite bar and gave it to me when he quit lifting.
If you don't care about money, get the elite bar. If money is an issue, get the nybarbells. For myself, I couldn't justify the extra cost.
