Prima Klang vs Basic 5/8ths Full Hollow Dovo's

I was considering a Prima Klang but I wanted an honest opinion. Would there be a significant difference between the shaves of a properly honed basic 5/8ths 'Full Hollow' Dovo and the 'Extra Full Hollow' Prima Klang. (I'm getting great shaves from my Best Quality & I don't want to waste money if the Prima's are not that much better when both are honed properly)
