Whats more important Critical Strike Rating or Attack Power?

I am a level 80 Mutilate Rogue and I am having trouble replacing a trinket. The one I have now gives 114 Critical strike rating and the one with attack power is 95 resilience rating with a cd that increases attack power by 752 for 20 seconds the cd is 2 minutes. The only problem is that if I did replace the 114 critical strike rating trinket I lose 3% crit chance which bring me down to 28%.
