Most people tend to associate Log Horizon with Sword Art Online. Other than the most basic plot of being stuck in an MMORPG, the two shows don't have much in common. I'd even say that Log Horizon has everything that SAO lacked, and lacks where SAO excelled.
Pros: Internally consistent world, rich side characters, and many plot twists that actually do make sense in hindsight.
Cons: The animation feels sub-par compared to SAO, and the soundtrack lacks that little something that made SAO's soundtracks so iconic.
The show has a few quirks that you may dislike (sometimes it feels that most characters have a split personality in case of comedic relief, and the animation does dip into the large sweat drop when someone does something awkward style), but if you can let that slide, you will have a show with good pacing, interesting story filled with mystery, and a world that actually makes sense.
