They both revolve around jumping into MMO virtual reality games and are both set in the future. However, there are a couple differences. First off, the protagonists are complete opposites in all but one quality. Secondly, the depth of romance in the story in incomparable to Sword Art Online. So if you are looking for a deep romance between characters that develops fairly quickly, I do not recommend watching Accel World.
