Any aftermarket will be a significant up grade. I don't there is a tremendous difference in the different brands. Compare cost and options and pick what you like. The Spearco is a top notch unit. It was a little trouble to install. The lower mounting brackets took quit a bit of massaging to get it all to fit. Also had to dremmel the back of the grille a little.
