Let's see. In my opinion SAO is pretty nice.
Sword Art Online Arc is nice, the fights are also exciting. I really like the sword skills and attacks tho it's really good in my opinion. Alfheim Arc is kind of booriing, but at the time when Kirito fight a red haired man I really enjoy it because of the sword fights, also Kirito is using dual sword. But I don't really like the illusions shit. Gun Gale Arc is kinda weird, Kirito is being too OP with his sword in a Shooting game. The storyline isn't that bad, I think. Mother Rosario Arc is nice, a little bit touching and nice.
AoT is also nice, but it's kind of easy to guess the storyline. At the time Eren died, most of watchers know he'll be back from nowehere, and there you go. He came out from a titan and became a titan himself. Blabla, the fight scene is not that bad aswell, well I think it's just fine. Also AoT Live action will be released this year, or next year, I forgot.
Sooo, in my opinion both of them are fine animes. Pretty enjoyable, and not that bad.
