It will depend on where you live, but I would say that its transport links aren't quite as good as Whitgift's, mainly because it isn't very close to a train station, and for most of us with 10/11 year old boys I suspect that we want the journey to be as simple as possible. They also use Hewletts as their uniform supplier, whereas I think a school shop on site is easier (and I hate shopping in Croydon).
Yes, I am nitpicking.... But actually with whichever school you end up, the journey is important, not just for the daily commute, but also for all the evening/Saturday events etc.
