It depends on the nation you are playing, as to what lvl9+ bless is best.

However, blood, death and air blesses are weak compared to the others. With certain nations they do have there uses, a air bless with shadow vestels possibly for example.

Death bless however may be very powerful, someone hinted that a sacred mage blessed with D9 who cast a battlefield wide damaging spell got the 350% affliction chance on every unit effected. Is this true?

I have not tested it yet but if true would make death bless excellent.
