I'm not sure height is a factor, my wife is 5' also, and I've known at least one similarly sized lady who loves her Brooks also. To me the whole bike/ seat setup is the big factor, but then you also get into those intangible things just like with guys and various seats.
Personally, I’ve never found bike and seat setup to be that important. All of my Brooks saddles are comfortable right out of the box. I’m not even that picky with plastic saddles. My daughter seems to share my insensitivity, although my wife doesn’t. The only plastic saddles I have a problem with are the ones with cutouts.
