How? Topographical maps let me know exactly where to start looking for a stop without having to read anything versus having a mind map of the tube and needing to scan names
Maybe the stop density is different, but I just don't find that an issue, you'd have to be outside of zones 1-3 to have to walk more than say 5-10min in any direction to hit a tube station. (That'd be interesting actually: heat map of how far away nearest station is from any given point.)
Flip side is my knowledge of London geography is pretty appalling. (Relative to say where I grew up, not necessarily to other people. The range of local geographical knowledge is probably worse here than in NYC.)
Much of Manhattan is a grid so just a little bit of knowledge about what the non-numeric avenues are, the streets that bound Central Park, etc. are pretty much all the knowledge you need between about the Village and Harlem.
