Right. Here's my take.
Al Williamson & Archie Goodwin's stuff is fantastic. It's been reprinted in trade paperbacks. If they worked on it, it's probably good. I just discovered they did an adaptation of Han Solo at Star's End, which I intend to get, but I can absolutely vouch for the stuff they did otherwise. Their artwork has a very "Flash Gordon" feel to it, which is nice considering Star Wars is sort of the modern incarnation thereof.
The KOTOR series is also terrific, beginning with the very first appearance in Dark Horse Comics #7, I believe. You can probably pick these up as one of Dark Horse's "Omnibus" collections. I read the KOTOR stuff from that up through, if memory serves, the Sith War. The rest of it I don't know about, though. I didn't like the artwork for the stuff about the Sith Empire (separate from the Ulic Qel-Droma storyline, I mean), so I didn't pay much attention to it.
The Marvel stuff...I actually go back and forth on. I didn't read a ton of it, but what I did read seemed not to be as entertaining to me as the Williamson/Goodwin stuff. (Although Williamson and Goodwin did the Star Wars film adaptations under the Marvel brand, so those are good.)
The adaptations of the Zahn trilogy are also fun to read. I recommend checking them out.
I didn't read much of it, but I enjoyed what little I saw of the X-wing focused series.
Anything prequel-related I avoid, though -- including the Clone Wars stuff, the stuff about other Jedi before the purge, etc.
The Dark Empire I and II are also fun, and I think I remember there being a final chapter to that as well (a third entry, but not called Dark Empire).
Anyway, definitely check out the "Omnibus" collections from Dark Horse (which includes reprints of the Marvel series), as long as you don't mind a slightly smaller format than standard comic book sized pages.
