which would be better? or are they both pretty much the same?

 

Superior owns Fairbanks...Yes, they're both the same part.

Agreed they are the same part. Beware though I do not suggest using this servo with a stock band you need a band with the band lug eye area reinforced , Its will tear through here with the stock band. If your just looking for and upgrade for the stock set up I would suggest the sonnax version. Dont get me wrong we use the superior just with the apropriate band

 

I agree, this (the Sonnax 2nd apply servo) is easier on the band, as I use them in high HP applications, but I have seen the BW Hi-Energy 2-4 band go hundreds of passes with the billet servo, before losing the anchor.
