There's too many other factors involved to give a meaningful answer. The frequency response of the mic is probably the least of it since most really objectionable background noise is fairly broadband anyway.
The sensitivity and pick up pattern of the mics are probably far more significant than the total frequency response. Indeed, since the differences listed are at the high and low ends of the range, they likely don't make much difference--frequencies below 100Hz are so low that they're more felt than heard--and depending on your age, you might not hear much above 15K anyway.
If this is relating to your other thread where you mention the noise you're concerned about is from the tower for your computer, then that noise (disks and fans) is going to span most of the audible range anyway. Moving your tower, putting deadening material around your desk and playing with the positioning and aiming of your mic are the things you need to do. Changing mics will only be tinkering around the edges, not going for the main problem.
