I have recently bought the Liquid Freezer 240, and have thoroughly looked at reviews in many, many sites.
All of them say it is superior to the h100i, and extremely quiet. Push+pull is a bit better, but only push or only pull is quite good as well.
The fins per inch in the radiator are actually quite high, and it is a thick radiator, so you definitely need SP fans. But this is exactly what makes it perform so well.
I haven't been able to test it yet, though, since I'm on holidays right now.
(And my build is based on NZXT, so all fans are already white, which is a big plus for me)
EDIT: I forgot, there is one bad thing about the Liquid Freezer.
If you install it according to the instructions, the 'Artic' logo in the pump will be upside down.
I don't know if this will be a big deal for you, nor do I know about the consequences of installing it with the logo right side up (as many youtubers, for example, have done)
