I have both and while I like my Jacked, the Pin Hacker is something special.  In my hand the Jacked is very strong and fairly angular on the backend.  It is a great choice for when the pattern opens up and I need to take that giant step in and still get recovery.  On the other hand, the Pin Hacker to me is the definition of a benchmark ball.  I have not yet seen a condition where I couldn't create a look with the Pin Hacker.  On fried up house shots, I can get in deep and hook the lane with the PH or on tight sport patterns I can square up and roll the PH up the boards.  I bowled all 9 games at Nationals this year with the PH and scored very well.  One caveat about both balls though, I did not care for the box finish on either.  Out of the box both reacted squirty, I found my Jacked to react best with 500 abralon and Brunswick Rough Buff.  The Pin Hacker I left at 4000 abralon no polish. 

I haven't thrown the Pin Hacker but I can tell you the Jacked is a truly amazing ball. The surface takes to surface adjustments better than any other ball I have thrown. At 1000 or 2000 abralon the ball is a great control ball that reads the midlanes well. Now if you take this bad boy up to 3000 or higher you created a beast in the backend. It will still read the midlanes but just becomes a whole new animal in the backend. Right now this is my favorite Lord Field bowling ball.
