This is the latest primary school SAT results - http://www.standard.co.uk/news/education/school-sat-tables-results-for-every-london-state-primary-a3421116.html -- useful once you start to find the areas that you like. For what it's worth, we're in Herne Hill and love it (moved from East Dulwich) Brockwell Park with the lido is lovely and the velodrome on Burbage Road both great for kids. We like that you can walk/bus easily to the tube in Brixton. For Canary Wharf, its a quick bus ride to Denmark Hill and then the Overground. Kids on our street go to a mix of Bessemer Grange, Corpus Christi (catholic), St Saviours (C of E)and Jessops and Charter for secondary (or private) But the reality is that all the areas you listed are great areas and the only way you'll work out what works for you is to spend a proper amount of time exploring them
