Eibach/5100s set @ 0 or Stock springs/5100s set @ 1.75?

I've researched quite a bit on the billies and have a question that I didn't see addressed when I was searching.

I'd like to lift the front of my 2013 TRD Sport PreRunner and am debating between getting the 5100's and eibach springs (no pre-load) or preloading the stock springs and setting them at 1.75. I read that the eibach springs have a higher spring rate but how does the ride compare to a pre-loaded stock spring. If anyone has any input or comments, please share. Thanks in advance

I've heard that pre-loading your stick springs will give you a harsher ride and thats just common sense. My buddy has 5100's with the Eibachs and his ride feels pretty nice.
