We played a 200 point impromptu scenario. Played on a 4x6 table. Rebels had to travel the length of the board and escape with their yt1300 and yt2400. 
The Outrider performed well but spent most of the game running and escaped barely with the Decimater on it's tail. The Decimater likewise was fun however it only scored 1 point any time it fired. The best damage it did all game hitting 2 Xwings that were chasing it with a proton bomb. That splashed one of those Xwings and damaged the other.
I also had a good hit with another proton bomb delivered by a bomber; that one caught 2 xwings, a z95, and also singed one of my TIEs. That one did not end well for the headhunter.
Both ships are fun and capable. However both require a bit of extra points to make them more capable.
