BIABH and Highway 61 are more or less equally brilliant for me. tend to cite BIABH as my favourite, got great songs and a bit of everything you want from Dylan all in one package. though Highway feels a bit more heavyweight in a way, feels like it’s got a bit more gravitas that lends itself a bit better to Greatest Album Ever discussions.
Blonde on Blonde and Blood on the Tracks are both solid records but people who cite either of them as his best over the above two are just massively wrong tbh.
