Coilovers work well for some while springs work well for others. I have both. Not both on the same car...but different cars serve different purposes and I felt the daily driven BMW didn't need a coilver kit because I was never going to adjust the dampening or the ride heigth, basically eliminated the need for coilovers. My prelude on the other hand needs to be able to adjust and therefore I have coilovers on it. I wouldn't knock either of those two H&R kits that the tirerack sells for our cars one BP was referring too $600-$679 and they come with MATCHED shocks and springs. Both kits are decently priced and H&R is tried and true. A Good coilover kit starts around $900-$1100) OP: Figure out if you want/need adjustability and go from there in making a decision.
I have the H&R race springs. My rear struts were shot and I put in Bilstein Sports when I installed the springs. The fronts were never touched, my stock shocks are still fine. Just had one off a few weeks ago, not leaking, still works flawlessly. Since installing the springs on my stock front struts...I have auto-x'd my car 4 times, and had it BeaveRun for a track day, and put just shy of 8k miles on my car...everything so far so good I inspect them often
