Contour Next vs Contour Plus (strips and accuracy)

Can someone guide me please on what's the difference between Contour Next and Contour Plus glucometer. Do they both have the same accuracy? I am asking this because the cost of strips for Contour Next is almost double the Contour Plus. If results are the same then why this difference?
