The Swarm. Parasitic Skies is just fucking ridiculous, an absolutely savage record. When some of those guys went on to do Cursed that was them toning things down and getting a bit soft.
Propagandhi are easily better than Fucked Up as well, and possibly better than The Swarm. That's a tough call though. And Chokehold, Content With Dying is a beast of an album. And Left For Dead are better too, obviously. Can't count out Shotmaker either, they were fantastic. And hell, I still really like Submission Hold even if they are a bit cheesy and I'd probably take Progress (As If Survival Mattered) over any of Fucked Up's records.
