I think Brad seems very comfortable with both Jenni and DeAnna. Jenni is my favorite but I would be okay if he chooses DeAnna. Both seem like their personalities would mesh well with Brad and his lifestyle.
I've mentioned this before but to me Bettina always seemed so awkward and uncomfortable that it made me feel that way watching her. I'm surprised Brad kept her this long. I'm glad she was able to make a classy exit.
