Not a Disc expert, and don't have a lot of power, but I've compared them throw for throw. For me:
Trespass was less stable, could turn it over easier, and I got better distance that way, at the cost of predictability.
Destroyer really depends on the disc you got, but overall mine were more stable, more predictable with straight to slight fade when it was gliding, but I often failed to get much turn on it, and thus got less distance for the same power.
Both of them have a nice straight line, not too much turn or fade, when thrown well.
For me, the Tern is a better choice since I don't have the power. It has a nice S shape when throw correctly, can throw with hyzer or anhyzer and get predictable results. My favorite plastic is now Gstar. I had some awesome park jobs and all time best drives for a hole with it over the Holidays. It just seem to get a cleaner release with the Tern as well and can hit an early window with it as well as my Fairway driver.
