if i understand flavors correctly, over half tend to choose liberty. i'll list the AIs in their preference for opening with liberty. note that flavors change on a game by game basis so this doesn't always apply:
catherine
augustus
napolean
kamahameha
alex
isabella
montezuma
suleiman
washington
elizabeth
genghis
bismarck (honor second choice)
oda and pacachuti are 50/50, both split with honor
hiawatha and ram both barely tend to choose tradition
harun slightly more inclined to tradition, harald honor
darius tradition
then there are those who will very rarely choose liberty:
i think gandhi will always choose tradition,
wu tends tradition,
ramesses tradition,
neb tradition / askia honor
