What school harrow or radley?

I suspect academically there's little to choose between them neither are in the same league as super selectives like SPS and Westminster. Harrow is all full boarding and that will influence its ethos, when my DS was at prep is had a reputation for having parents who were screaming snobs, it was often the second choice of the very wealthy who's DS's hadn't made it into Eton. Unlike a couple of other traditional boys boarding school it does not have a very generous bursary policy so the cross section of backgrounds the boys come from is likely to be pretty small. It is very traditional and I've heard from a friend with a DS who was there not good with the unconventional and quirky. Dulwich on the other hand is primarily a day school so a different ethos and of course lower fees, it used to offer at lot of assisted places (maybe it still does I'm out of that loop now) and from what friends say who live very near by it the boys come from a wide variety of backgrounds.

The son of friends from HK has also been offered a place at Harrow and Radley. They like both schools, but would like to know which is stronger academically. Does anyone have a view on this?

Rugby is big at Radley on the circuit they are the ones to beat if I was looking for a top rugby playing school Radley would be my first choice.
