Hursty Is north or south London better generally? I always thought North had more going on but I have literally no idea.
Speaking relatively objectively, ignoring Central/Zone 1, the nicest parts of London are North-Central (eg Islington/Hampstead/Highgate) and South-West (eg Barnes/Richmond/Wimbledon Village).
Most of the rest will have a pretty even smattering of alright bits and dumps (except for East, which is more dump).
Ignore Smalls (as if that really needed verbalising).
