While I don't have 1st hand experience with both, Eibach's are not really highly regarded from all I've read. You can see their rate is also a bit on the softer side (unless you get slammed on race springs). The BMW PS on the other hand I've not read anyone complain, to the contrary. I'm super-happy with my ride now compared to ZSP, but it's not only the yellow spring I've put on...

Just make sure you use the correct bumpstops for the application.
