Hi - i know this thread is really old but just incase anyone is looking for an 'up to date' opinion here goes:
My son goes to Davenies. When choosing, i also looked at gayhurst & Kingscote.
Kingscote -I was impressed with 'Kingscote' (pre prep) but not so impressed with 'thorpe house'. Its very small & i was concerned about social skills amongst other things, so decided against it. Good pre prep facilities & outdoor area.
Gayhurst - well i did not see one person smile in that school!!! - including the staff!!! We were shown a music class when we were being shown around and the teacher didn't talk to the boys - she shouted at them, unnecessarily so in my opinion. Yes they do very well at sports but I am much more interested in the rest of their education & more importantly their happiness. I would not send my son there.
Davenies - The first thing i noticed about this school was how happy the children are. I also noticed the childrens impeccable manners and their confident social skills. It has great facilities and seems a 'fun' and happy school. (forget chess club - these boys can do paintballing, go karting, skate boarding, fencing - as well as the more traditional options of course!)
I had to laugh at a previous comment which mentions 'snobby parents' at Davenies - i think these people exist all over south bucks unfortunately!!
My son is in Davenies pre prep. So far i am very happy with Davenies and feel i made the right choice (even though gayhurst & kingscote are much nearer to where i live) More importantly my son is happy. He likes his teachers and i have noticed how very much he is learning. There is a big emphasis on lessons being specifically geared up for boys and also picking things up in their own time - they discourage 'pushy parents'.
In fairness I think you just get 'that feeling' for whats the right school for your child.
Anyway - i hope this helps someone!
