Berkshire is a long, thin county; surely it depends on where you are. If you're at the east end, then there's White Waltham, Booker (strictly Bucks). If you're at the west end, then there's Thruxton and Oxford. If you're in the middle, try Blackbushe.
It really is best for you to check out the schools yourself; what one person might see as a strength in a particular flying school, someone else might see as a weakness. Only you know what you want to get out of it.
