Best areas for secondary aged DC London

[GailSnail]

Inspired by reading a thread about teenagers growing up in London. Which area of London do people think is the best to live in, if you want state schools (not private schools or religious schools)?

Any experiences on here of happy London families with teenagers?

(Disclaimer - I currently live in Greenwich which is great for primary but secondary schools aren't the best.)

There's been a new principal at Graveney (I think she started as an acting principal in 2020) who seems to be much more on board with promoting equal opportunities in education and diversity of all types.

Early days, but signs are encouraging so far (the caveat being that I only know from my experience and so don't know everything!)
