The question is , Op - which school does your ds prefer? and you?
You cannot possibly expect anyone on this board to have direct experience of both schools because they are in completely different cities. And even the craziest of QE parents (and there are more than a few) wouldn't force their dc to commute from Birmingham to Barnet. I hope.
Your ds must have visited the schools in order to take the exams, so I am presuming you accompanied him? what impressions did you form?
You have itemised your criteria and explained them in your post, so clearly you have already answered your own questions.
I have no idea about house prices in Birmingham but I can tell you that I live near High Barnet and house prices are crazy.
