Claire is the strongest of the four. She doesn't take shit from nobody and is willing to bust a cap in somebody's ass if she was given the chance to.
Rachael is the second strongest, she just has too much unnecessary drama going on with this love triangle between her, Luke, and Amanda. When pissed off, she is one hell of a crazy *****.
Kate is third, she just needs to stop letting people toy with her emotions.
Rose, she has potential, but she has too many problems to deal with as is.
I miss this show.
