I would imagine the better of the two would be the FK's, however, the AP's are really good for the money, I have a set on mine currently and the ride is good.
 
how long have you had them on? i see yours are right down so how low is that?
 
They have been on there about 10months...The backs are all the way down on the adjuster plates, not sure how low the fronts are, it's taken a little bit of adjusting to get them at the right height so they don't rub too much etc.
