Honestly, if you wanted my opinion, F3F > This.
Don't get me wrong, Absu headlining is a fuckin' great thing, but if I had the three day pass for the festival (especially since it's in Austin as opposed to Houston), I wouldn't even think about going anywhere else.
Plus, the others keep mentioning all the bands you'd be skipping, and they're making a pretty good point...
12/3 - Morbid Angel
12/11 - Megadeth
12/12 - Suicidal Tendencies?
12/14 - Combichrist?
1/27 - Phil Anselmo
5/12 - Nile
