I go to Adoration every Friday evening. I find the Divine Mercy and Eucharistic adoration similar, as far as what I'm trying to pray, and contemplate on. The Crucifixion, Eucharist, the sacrifice that Jesus did for me, etc.
BTW I can't recommend Eucharistic Adoration enough. For myself, I find it the most peaceful and distraction-less part of my week. It's one of the beautiful things of being a Catholic. I go to adoration on Friday from 7-8, and am usually by myself in the Holy Presence. I'll pray, mediate, read pious books.... Our church awhile back had 24/7 Adoration, but it closes up at 8pm now.
