Madan no Ou to Vanadis

Although at the first glance those two anime does not look similar at all, watching war maidens in Mandan no Ou to Vanadis fight reminded me SAO fights... Especially when they were fighting dragons (or each other) and using all those supernatural moves ^^ Also, in each series there is an outstanding guy whom all girls around him start to like XD
