Underlayment for Laminate floor

I am getting ready to have Columbia Clic installed in my kitchen and family room. I have done a lot of research and I am pretty sold on it. First of all do you have any opnions on this product?
I am also having a hard time deciding on an underlayment. The floor will be installed on top of concrete. One place that I am looking at is insisting that I use Hush step underlayment. I have also looked at a place on the internet that uses 3in1. Both have a moisture barrier and the Coumbia Clic also has a moisture barrier built in. Is there enough of a difference that I should pay more for the Hush Step? Thank you!!

 

If you desire an acoustical underlayment take a look at Tranquility or Silent Walk. They test out similarly and the results are really much better than others I've seen. These products are sponge rubber not a plastic foam.
