The one you like best has the best response and you should keep that one. If you can't tell the difference then flip a coin
the charts will usually tell you how the mic performs with a 1k test tone at 1m. If you are recording 1k test tones at 1m this may be important information but otherwise it is an extremely loose guide to some of the mics generally properties and not really useful as a sole source of information for choosing one mic over another (espicially if you have the mics in your hands and can test them to see which one you preffer for your applications)
