If you'd like to have infinitely adjustable height, and have a smooth ride you could buy a air ride conversion setup and get rid of the steel springs altogether. Add a tank and compressor and you can dial your height from inside the car. I converted my 1 ton dually from steel to air, and would never consider steel again.

Cheaper than coil overs and the ride is hands down better than steel springs. In the end it depends what you want.
