I don't find London to be dirtier than SF. Also I get the sense that it's a much bigger city in general, and of course your Stratfords will differ significantly from your Westminsters, although this can be said about basically every city.

Also I think London is slightly cheaper. Still, working remotely from London proper is probably a terrible idea given the extent of public transportation. Just live in Croydon and catch overground to London when necessary IMO.
