I know it's a dumb meme, but strong disagree on grid cities. They always violate the natural landscape of the city, and are only easier to navigate if the land is very flat, or if you are driving.
The windy roads of organically developed cities look confusing on a map, but are often way easier to navigate and understand when on foot. Wayfinding is instead done in terms of natural features, e.g. go downhill towards the river until you hit the main street.
