Follow The Reaper...
The solos are more original and not neo-classical wanna be's... the songs are laid out and written better (especially Janne's parts), they're all more experienced musicians... the production is a LOT better, Alexi's voice sounds better... What else? Better songs all together, I mean, that is more personal opinion, but...
Oh yeah, it doesn't have a following of "hatebreeder only" fans who still cry themselves to sleep because CoB changed (for the better) with Follow the Reaper/HCDR/AYDY.
