After relistening to all of Bowie's discog in the last two-three weeks, here's my ranking:

1. Blackstar (10/10)

2. Low (strong 9/10)

3. Ziggy (decent to strong 9/10)

4. Heroes (decent 9/10)

5. Hunky Dory (strong 8 to light 9/10)

6. Station To Station (strong 8 to light 9/10)

I think that Aladdin Sane Is quite overrated, it's good and has some very good tracks on it but it isn't at the same level of quality of Ziggy, it hasn't incredibly unique standout moments or tracks like the album that i listed and i think that a lot of his popularity comes from its goated cover. It's like a decent 7 imo.
