I guess it will all depend on your preferences if you use exalted angel or battlegrace angel.

They have there pros and cons, but what i don't like about the battlegrace angel is that she can't be used as a blocker for cause 4/4 is kinda weak, yes she costs 1cc less but its like playing a serra angel. yes she would have a stronger offensive power by 1 point compared to exalted or serra if shes the only one that would attack.
