All CoB's releases kick ass.
I would probably rank 'em like this:
1. Hatebreeder (just purely amazing with songs like Bed of Razors and Downfall)
2. Hate Crew Deathroll (aggressive and heavy)
3. Follow The Reaper (funny melodies and solid songs)
4. Something Wild (a really great album though it lacks a bit compared to the rest of 'em)
