It’s hard for me to rank the soundtracks, because unlike the films the quality is pretty damn consistently high.

Still - ANH and TESB are almost certainly #1 and #2 in some order… I’d probably put ANH first just because it was #1 and that movie might actually owe a decent amount of its success to the soundtrack.

I think the PT soundtracks (especially ROTS) are somewhat underrated here (although I would agree that AOTC is probably the worst soundtrack, although unlike the film the soundtrack is still very good). Just imagine how much more awful those films would be without William’s brilliant work

I also think the Rogue One soundtrack is very underrated… there been a decent amount of “It’s not John Williams so it’s obviously worse” when I don’t think that’s the case. In fact the ending of Rogue One with “your father would be proud” is some of the best music ever in a SW film.

Overall I think all the soundtracks are at least very good and many are great/fantastic.
