I have BC coilovers. Got them on sale, and a good set. Ride is pretty good considering how stiff they are. I am still trying to perfect the ride height, and right now am battle-ing a creaking noise, but I know its from my install, and not the set itself. I dont know how any of the other sets are though, but I would recommend these.
If I was to go a different route, my only other option would be H&R springs, and Bilstein shocks. That setup was only 85 dollars cheaper than what I got my new BC's for, and required a more involved install. I do not think I would go H&R coilovers as there is no damping adjustability, and they cost more. Given how much of a pain it is to actually adjust ride height (raising the car, removing front wheels, removing the rear shock lower bolt everytime you change height) and then waiting a week to settle, I am less inclined to alter ride height that i thought I would be. Therefore, [for what its worth to me], if you can get coilovers on sale, I recommend BC's, but if not, and you dont want to jack your car up every weekend for a month straight, go with shocks/struts.
I guess the real decision boils down to:
1. How much do you want to spend?
2. What kind of driving are you looking for? Autocross, or daily driver with attitude?
