Which springs, Eibach Pro-Kit or H&R sport?

What do you think, which springs, eibach pro kit or the H & R sport will be more down my Octavia? Both manufacturers for Octavia 2 have to offer that springs lift down about 3 cm. Now, how it looks in practice? Supposedly, I heard that people are not satisfied with how the Octavia down with Eibach Pro-Kit, said that it was not even close to these declared 3 cm .. In practice, it is up to 1.0-1.5 cm..What is the situation with H & R Sport Springs? They declare the lowering 3.0-3.5 cm down .. Is there someone who has their car lift down with H & R sport springs?
