Real world not a lot of difference in performance tbh, usual rules buy the best conditioned one etc apply.
4.2 IMHO has better inherent intake to give crisper throttle response. Early 4.2's have small journal crank that can snap and very wild cam, however both of which have probably been changed out by now. The 4.5 is smoother at low revs, so better in town and feels longer legged with more torque. Late 4.2's have 4.5 bottom ends (so they are actually 4.5's) but with the 4.2 intake, best of both worlds, again IMHO.

Use the search facility there is a thread on this at least once a month plenty of opinions to be read.
The last 3 of them have all been started by the OP...Why keep starting new threads asking exactly the same question?
