She has NEVER seen Angel? Well, that must be corrected ASAP!
I think I love Buffy with my heart, but (except for S4 Cordy) overall my head thinks Angel had better arcs and stronger character development. Wesley in S4 and S5 is a marvel, as is Gunn. The whole exploration of the nature of evil and the questions of life are handled with more subtlety and sophistication.
