Immolation.
Incantation is gold as well, just not as much weight...I only really listen to Onward To Golgotha, Mortal Throne of Nazarene and maybe sometimes Diabolical Conquest...Their newest doesnt really peak my interest enough to even check it out tbh...
Immolation on the other hand, almost their entire discography is legit. Id argue that Immolation has 2, not 1, top 10 death metal album spots with Dawn of Possession AND Here In After. Fuck man, they have SO much good shit. Unholy Cult is fapptastic, Failures For Gods is fucking badass, and Close To A World Below is sick as fuck.
Clearly Immolation has the upperhand in this battle.
