I'm probably about to speak blasphemy but I think I like Presents better than the older stuff when Jeff screamed un-amplified. I actually has nothing to do with the vocals I just like the style better. It is perhaps without some of the earlier raw emotions but you get more content per song. That is to say there isn't 30 seconds of feedback on a 45 second song.
"Easily the worst screamo band." - You've only listened to early stuff, haven't you? I can't even begin to count how many horrible screamo bands are around just right now, all of which are worse than this in every way.
