Both are very similar heads, I was torn which one to have my wife shoot last year. The montecs are a tougher more durable head but have a 1/16 less cutting diameter and arent as sharp as the hell razorsout of the box. Its a toss up, my wife shot the hellrazors and was 4 for 4 on deer last year with the biggest being a 140" 8pt that field dressed 200lbs. None of the deer she shot made it over 60 yards.
