well for me, i learned WTLF first, so that's probably the easiest.
Other songs that aren't too hard:
Torn, My Own Prison, One, With Arms Wide Open (if you can do olb, you can do this no problem), Never Die, Wash Away Those Years (bridge might be a challenge depending on how good you are, but it's not that hard), My Sacrifice, To Whom It May Concern
I'm actually best at the finger picking songs, i like them a lot too.
My Own Prison will take a little time to get the hammer ons to sound good, but once you get the motions down it's no problem, plus it sounds cool hehe.
Ode also isn't too hard, but it's like the next step up from the ones above.
Hope this helps
