Manual hubs are a big improvement over auto hubs! But IMO warn, MM, Superwinch, newer spicers....etc.... are all about the same and all are external driven. So I would buy whatever is cheapest. If you want a good set of manual hubs find a set of spicers off a 70's d44. Alot better than any of the aftermarket crap!!! Thats my 2 cents. Good luck.
