Well if you compare MMO, SAO has not specified roles  or classes, it is just mainly reliant on sword skills and weapons. Log Horizon is very technical on the MMO classes, levels, and mechanics, such as buying buildings, guilds, user rights etc. SAO only touches on those but the way it is structured it goes to the extremes of playing, mostly solo with making connections to others. Well the specifics are many but that is just the overview.
