My understanding is the Eibach Pro-kit is:
Front: 148 lb/in
Rear: 456 lb/in
which is lightly higher rate in the front but lower in the rear. I got that info from the suspension section sticky, it may be wrong. I haven't seen any info on the H&R spring rates.
Do you like Bilsteins better than Koni's? I haven't been in a car with Bilsteins in many years. The Konis drive really well and comfortable.
