Hi, im having the same wait for my DS. We looked at both and it is hard to tell just from visiting what they are like. In my opinion ( and it is only my opinion ) I think KES seemed a lot more elitist than AGS, similar in ethos to SGGS in fact. I think the expectations placed on the boys will be different. Don't get me wrong, as my daughter is at SGGS and she revels in the elitism of an all girls school. However, my wife thinks AGS would be a much better fit for my son, as he is very much less bothered about that kind of thing. He also likes being around girls, whereas my daughter thought that boys " waste my time in class ". I also know people who chose AGS above KES because they thought it a better fit for their boy ( above AQS received for both AGS and KES ), they are very very happy with AGS. So, in short no easy answer.
However, if he does do well enough for KES, it will be a nice conversation to have with him about where he wants to go.
