There all good,matter of personal prefrence & how much you want to spend.If you can afford it get extended radius arms & rear springs instead of blocks. Just my opinion
well u really didn't give us much to work with, what size tires do u want? what do u use the rig for, daily driver, mud, rocks?? what is your budget?? these are key things to take into consideration, once u know all this then u can look at each lift brand, and see what they have to offer and how much it will cost.
