My favorite album is the second stage turbine blade, but good apollo volume 1 is definitely a close second.
I don't actively dislike any of their music though, even the new stuff. I'm a huge fan of the variation in their sound, and I personally favor acoustic/emo and pop punk in general.
I wouldn't say that they have fallen away from their roots necessarily. Some of their earlier stuff is really melodic and soft. Like the prize fighter inferno stuff.
