You can't go wrong with either shock. FOX has the stronger brand name so it fits well on the TRD Pro. The FOX QS3s were tuned for more "off-road" focused driving (go-fast events with dialed compression and rebound valving). I would bet that the FOX shocks are stiffer on-road for better performance handling and they soften up as you progress into faster shock events. The OME shocks are based on the OME MT64 body with a redesigned internal specifically for the TrailHunter and are more tuned for overland stuff. Probably softer on-road for better ride comfort. Either way, both shocks will perform out of the box for most drivers. I doubt that many people will be able to tell the difference between the two unless they drive them both back to back on-road and off-road for hours on end. At the end of the day, most of these shocks are going to get ripped out and replaced with "better" high-performance, longer travel shocks anyway; KINGS, Fox race series, Dobinsons, Dirt Kings' new line of shocks, etc.
