I prefer Junior at long time control because Genius is a root processor and can
changes it's evaluation after actions like trading queens.

I think that in this tactical position it is better to play the first 10 moves
at slower time control (at least 10 minutes per move) because it is important
not to miss something tactical.

I can tell you Junior5.4's and Genius3's moves with white at slow time
control(at least 10 minutes per move.

Junior follow the game and play a different move only when it choose Kd1 or Kf1
instead of Kd2 when Genius3 choose 17.Ne4 Nf5 18.Nfg5 Bxc5 19.Qg4

I do not know if Genius5 or Genius6 is clearly better than Genius3 and this is
the reason that I did not buy Genius after Genius3..

I knew Genius3 is good after it beated kasparov and there is no reason to buy
new Genius when there is no clear improvement(at least 40-50 elo rating
improvement)
