I'm not sure what specs the springs are, not 100% sure if both company's do 2 different rates of springs, but just a quick write up on my findings between the two. Both cars are riding on Bilstein shocks also.
The Eibachs(my car) are definitely lower at the back than the H&R's, by at least 10mm, but it's the H&R's that's lower at the front, by a similar 10mm at least just looking at it. So we have a car slighty pointing upwards at the front with the Eibachs, and with the H&R setup, it's diving downwards like it's under braking, but parked up of course.
Driving them back to back, the H&R's are much bouncier, especially at the back end, and looking at the springs through the wheels, the H&R(red springs) seems to have the coils fully compressed and loaded against each other with a black rubber coil protector to prevent damage, and only the lower 2-3 coils offering suspension movement, which would explain the bouncyness. The Eibachs(Black springs) though, despite sitting lower just looks like a normal coil spring and seems to have full suspension travel/movement and slightly progressively wound, so firmer the more they compress.
The front end of both cars ride reasonably well for being uprated and lowered, but again, the H&R's ride slightly firmer than the Eibachs, just slightly firmer that OEM suspension, not as hard as a coilovered S3 I tried in the past by someway.
I have to admit, I prefer the front end stance of the H&R setup, but the rear end of my Eibachs, so something inbetween would be ideal, and looking at Tuffty's car riding on APEX springs, that could be ideal, but I've never sat in his car, so can't comment on ride. But with either the H&Rs or Eibachs, both ride very well, as close to OEM ride as you could get going aftermarket, but the H&Rs just felt a bit bouncier over rough roads, the Eibachs are very comfortable.
Can't really do a handling comparison, as my car is running 19" rims, the other S3 on 18's and also had Forge adjustable tie bars and Neuspeed ARBs, so handles better than mine in the first instance, but even with all these additional mods to aid handling, you still can't feel how much grip the chassis has. It's like the car turns in great and has plenty of grip, but you don't know when or if it will let go, I didn't push it to absolute limit for obvious reasons.
