Personal taste, you know I am obviously speaking from my opinion, so wrong how? :]
I dislike some of Andy's stuff for how much he goes on about Jesus and God, I wouldn't mind if the references were smarter like mewithoutyou, but he straight up puts Jesus/God into a good portion of his songs which doesn't appeal to me at all, it seems like his weakness, come up with another metaphor please, overkill. Then means everything to nothing all sounds too similar and the standout is the EP song I can feel a hot one... I also only love tracks 3 - 7 on simple math, the rest is boring to me, DATH have two solid albums I do not get bored of listening to/can go back to.
Also the dear hunter, I liked a few tracks off of ACT III, he has such an awesome voice, do not know what else to listen to/what is better by them.
I have my own solid reasons, what are yours? :]
P.s. also DATH do not take themselves as seriously, with the whole concept album and Andy stuff in general, just have more appeal, though I am a big Manchester Orchestra fan, if my parents got in the car I would more likely put DATH on.
