The only counter-argument I am aware of is that "It will get better as software and training improve." I don't doubt the veracity of this statement, however with the whole JSF fighter project falling this far behind schedule there is just too much uncertainly in how long it is going to take it to "get better" and how far you can push the airframe which is, as everybody can agree with, somewhat mutilated from the beginning.
