To be fair... I would almost guarantee that has more to do with them having to replace almost all of the linkages and the steering box in order to accomplish the change to crossover steering than it does with that type being better for normal driving. I have 35's, a 4" lift, and normal stock steering components. The steering got infinitely better in feel and got rid of all of those things when I replaced my ball joints on the drivers side, rebuilt/adjusted my steering gear, and replaced the rag joint on the steering shaft with a jeep one. Most dodges and Fords have crossover steering from the factory and are well known to be prone to death wobble when components start to wear out.
All that to say, my steering box is about done, so it will likely need a replacement soon. It about double the cost between just replacing the one I have and staying standard and changing over to the crossover steering using an ORD kit. I'm seriously considering it... we'll see. If you have the extra $500, then sure. If you go heavy wheeling and need it, then by all means. But don't think you NEED to do it in order to get rid of drift and make your steering responsive. Chances are you just need a quality steering box replacement and to check your steering linkages.
