Joy has a bunch of great songs but Crawler has more texture and doom sounds. I think in Crawler you can hear a lot of what they've been doing on previous albums become more coherent as they've become better at it. I do like the immediacy of some of the early bangers but they obviously spend a lot of time crafting a vibe. Ultra Mono is for me a slightly better album but I don't think many would agree with me - it's probably more consistent good without quite hitting the highs of Car Crash and Beachland Ballroom (two songs I don't think I'll ever tire of listening to) although Grounds and A Hymn run them close (both pairs have a lot of similarities)
My opinion on their simple outlook is I do find it a bit cringy at times. I always try and look for nuance and perspective however that can sometimes lead to nothing changing. Sometimes you do have to just draw a line in the sand and say this should be different and not really worry about the nuance.
For me Joy and UM are collections of good songs. The songs might even be better, but Crawler is a proper album. I am still not that impressed by Tangk, think it is their weakest to date, and I think they are struggling trying to unnecessarily keep themselves reinvented.
