The list suggests some recency bias (Roger Bacon 1990, notwithstanding) and small-school bias (no D1 Ohio schools for boys or girls?!). And top 4 for from Ohio plus 1 from Kentucky suggests a desire to include a team from across the river (surely very deserving). For the boys, the only undefeated Ohio team on the list is Turpin 2001. Among some great teams (many undefeated) left off...
Girls: the St. Ursula teams were unbelievable (I could choose from several that might be #1), Loveland's recent D1 state champion (thinking they beat one of the Indian Hill state champion teams from around the year of the list, maybe the year before), last season's Lakota West team, back-to-back state title Badin teams (led by future NCAA champion, Malia Berkley), some awesome Fenwick teams, and an undefeated Madeira team in 2010. I know I'm missing many other great ones.
Boys: Cincinnati was dominated by Finneytown in the 70's and early 80's. Multiple state champions, including the first tournament when there was only one division. St. X had a big-school state champion in 1983 that must have been amazing. I played against Turpin's 1-loss AAA state champion in 1986 (my team gave them their lone tie by bunkering), and they were phenomenal. This was Turpin's only top division state champion. The Summit Country Day team of 1999 led by Jack Cummings (South Carolina), Jamal Shteiwi (national champ Indiana), and David Koch (Cincinnati) may very well be the best ever Summit team. Mason's undefeated squad in 2013 is Cincinnati's only D1 boys state champion in the past 34 years. And, of course, my aforementioned undefeated Madeira teams of 2002 and 2003.
Of teams that did not win state championships, on the boys side the Lakota West team noted by SuperFan555 above that fell short in the state semis was incredible. In 2006, Fairfield gave up only 4 goals all season before losing in a goalless pk shootout in the state finals.
