I think that deciding based on 1 or 2 games is not the right thing to do.
I believe that Amir worked a lot about the evaluation function of Junior and I
believe that Junior7 must be stronger than Junior6.
Junior5 was stronger than Junior4.6,Junior6 was stronger than Junior5 so I have
no reason to believe that Junior7 is not stronger than Junior6.
I know that there are good moves that Junior7 can find and Junior6 cannot find
and I believe that this case is more common.
