Actually, I preferred the SAO arc the best. ALO was fine I guess, but it offered closure to the SAO arc.
IMO GGO was not quite as good as the previous arcs. It felt kind of detached from the previous storyline. (Even Kirito's character development seemed pretty lackluster.)
Wish the author expanded on the main SAO storyline more instead of ending it on Volume 1 and just adding sidestories...
(On a sidenote, Volume 9 was very interesting. I'm eagerly waiting for Volume 10 to be translated.)
