Best ifs kit? rms, hdk, gt suspension, or magnum force?

After looking at these aftermarket suspensions very thoroughly, I made the choice of the GTS, it seems to know doubt be the strongest, and his geometry looks superb, good camber gain, amazing bump steer, and great suspension travel, also found out his b/e body kits have 7 inches of travel, obviously more room toe get a longer coil over in, and his a bodies just shy of 6. Very excited for this, and I really think this is going to give every kit out there a big run for their money in all areas!
