I've been doing some math and I actually think with high PS pilots, Predator might actually be more powerful than Opportunist. Specifically because there is no added stress component, which either limits your future maneuvering or limits future uses of Opportunist until it is shed.
When running on a PS8 or 9 pilot, you will get 2 dice rerolls on all attacks. Combine that with the ability to take focus and significantly reduce the chances of rolling a miss on your dice.
I loved running Wedge + PTL + R2. I would Focus and Target Lock, to maximize his output. This cost me 4 points and whenever I used it I Wedge would be stressed (which also implied that I had to be able to use actions in the action phase.) Predator accomplishes almost the same thing, but at a point less and without the stress consequences (so no need for the R2 unit.)
So in the end the choice is:
Opportunist: Higher damage range
Predator: Higher probability of doing damage.
Course if you manage to TL + Focus + opportunist its much better than Predator, but thats relying on a multiship action combo.
