Totally depends upon the vehicle and usage. For a Wrangler, Kings first, although Radflo is the new hotness. For an FJ, ICON makes the best value pre-tuned multi-shock (2 per wheel) setup, but a case can be made for Kings or Radflo if only using 4 shocks. In any general sense, Kings and Radflos are really designed for high-speed desert racing, Icons a close third, with Fox a bit after them. The OMEs, Ironmans, and the rest are OK, but most don't offer a separate oil/nitrogen charge reservoir, which you want if hitting them hard in the desert at high speed. Nor are they as tunable as Kings, Icons, and Radflos. But let's be clear- you asked about "the best", and that ain't cheap. The best desert shock setups (8 Kings total including 4 multi bypass) will run at least 50,000 AED. Phase I of my FJ ICON setup just cost me 18,000 AED, and to add the Phase II multi bypass front shocks and rear bump stops will cost me another 12,000, at least. And I skipped the high cost options like solid aluminum billet upper control arms and matching lowers...it could have been a lot higher. So, you may want to consider what you mean as "best". And how badly you want it.
