which air pump is better Hailea or luft?

[tpl*co]

for powering the sponge filters (probably will have 4+ sponges on the thing and want it to be quiet)? I want a quiet and reliable pump.

I started with a shengo m2k3 and did not like it, very noisy(powerfull) , decided to buy the Luft and I am very pleased . It is quiet and has enough power for anything I need , I have one running 5 Hydro IV and a large Rena air stone and still do not have it at full power. I think the rheostat adjutment is pretty cool. It looks and feels like a quality product.
Someone here mentioned they liked the other pump you mentioned very much in a previous heading.
