I was super into THP when it dropped, but to me even tho it was a "fuck the label we do what we want" type of album and I can understand and respect the idea, to me it has aged horribly, it's my least fav in terms of Chester's vocals, he basically yells in some songs and I've got big problems with the first five.
KTTK and AFN might be my least fav LP songs to date (alongside with HTF, Nobody's Listening and In Between), GATS has cool instrumentation but the verses are so formuliac and lirycally it comes of as the stereotypycal "anti" song, except for the Rakim part that's cool, The Summoning is ok (quite useless but ok), War is fun but again, Chester basically yells "WAAAAAAAAR DESTROYERRRR", then from Wastelands on I like it (especially Rebellion and FM, amazing songs), ALITS is good but overrated IMO and the rap verse is out of place.
OML to me feels the opposite, I always felt they were all on board with the project and, even if it's not super creative in terms of music, it's super enjoyable, I remember liking every song upon the first listen sooo, yeah, it's very personal
Plus, the fact that Chester took singing lessons (vocal coach or stuff like that, you know better than me) was something really effective on OML, I love his delivery on the title track, NCSM, BS (that bridge is awesome) and Halfway Right (probably my fav song)
