i love the first half of WFIKTBD even more than TRITSIO, i think that's where they were at their most original and fluid. it's not as 'heavy' and 'dark' and 'primitive' as most acclaimed acts, i just find it to be sky-tearingly powerful music full of vivid imagery and intense emotion, and i've never heard a more unique death metal album right through the instruments, songwriting, production values etc. naturally it's gonna be an acquired taste as a result.
TRITSIO is extremely unique too but it has a little more old-school appeal because it's darker, extremely violent. but even then it's a more internal, psychological kind of violence, feels like it's shattering my mind into fragments, and you're vulnerable to these amazing emotional flourishes of theirs because you're immersed in such an unstable world. a lot of DM people don't really like emotion in their music the way ATG bring it. it almost serves a totally different purpose from most OSDM (although i challenge anyone not to headbang at least a little to 'kingdom gone'), so i've given up complaining when folks don't like it.
