Well done to your daughter for a good score
In answer to your question I guess it comes down to which school you prefer and also considerations like trave time etc. Personally if I was in your situation I'd leave bucks and just go for Langley since it is so close to you...I am in hounslow and applying for my child to go to Herschel (my dd got 131
) but am still stressing about travel time ... You are in a ideal position....but I guess you are the only one that can decide what's best for you and your daughter!!
Anyway best of luck with whichever decision you make
