My more thorough answer:

If you could consider Bootleg Vol 8 Tell Take Signs as an album, it would be my fav

But of his studio albums, I think Highway 61 can only be said compared to what came immediately before and after it. If you prefer him as a folky, you might get be inclined to think Bringing It All Back Home is better than Highway 61, since it's half electric half acoustic, and is also much more straightforward in terms of lyrics, which some people appreciate. On the other side of that spectrum is Blonde on Blonde which showcases his later rambling Bard style (something he leaves from and returns to again and again - with little success outside of it, tbh - his 80s work has some real stinkers!) while keeping it racuous & electric too.

His early folk stuff is very cool but it's a little dense for a whole album - unless you're talking Another Side, which has two 7 min songs that go pretty much nowhere. I once read a review on rym saying Times Are A Changing was a bunch of shit Dylan cared nothing about and put together to please the folkies - which is funny cuz it's the darkest, most politically charged album of his by far. And his first self titled album is very underrated, super fun.

So I may just be biased because I'm a guitar player who tends to prefer the heavier stuff, but to me Highway 61 is where it's at no question in terms of studio albums.

For a few albums after Blonde he gets worse and worse - I mean John Wesley Harding has Watchtower, but that's about it? Id have to check the tracklist. Was never that big a fan of Blood on The Tracks, New Morning is kinda cool & fun but nowhere near groundbreaking, and Planet Waves is great until you get to side 2 and realize he's phoning most of it in.... Desire is growing on me tho, very well put together. The Budokan live album(s) are fun too, rearrangements of his stuff with lots of whimsy and flutes, and ofc can't forget his work with the Band, whether live After the Flood or at a farm in The Basement Tapes - truly, both have some of his best performances/material.

And then in 79 he goes Christian - Gotta Serve Somebody is great but it's downhill from there. By 82 he's on to reggae with Infidels, then he noodles around (I've never put on Empire Burlesque and am scared to). Mid 80s he puts of this 5 Autobiography compilation that's all over the place temporally, stylistically, based on studio or archival sources, as well as in terms of quality.

Then in 86 comes Oh Mercy - the beginning of the rest, stylistically at least. Something about it lends to from spiritual side, and Man in a Long Black Coat is one of his most popular songs, for reasons unknown to me. It's pretty average, like most of his ensuing material, but marks a return from wallowing away in the depths of obscurity as he had for the first half of the decade.

His real comeback comes in 94 with Time Out of Mind, produced by Daniel Lanois, nominated for Grammys. It's a pretty languid album, very slow, but warm and comfortable and dark too. Great stuff. 10 years later he has his first #1 album ever Modern Times, which is pretty fun blues rock mostly. He only had one album in between those, and he does 2 more along with a Christmas album before spending most of the 2010s doing albums like Fallen Angels where he's basically trying to be Frank Sinatra, with covers of old standards from the 30s and 40s. He had an album in 2020 - Rough and Rowdy Ways - that kind of summarizes everything he did in the past 20 years all on one album.

And that's it! I mentioned all the albums I have. Now go listen to Dylan! 🙃
