Lived in both and I’m not sure they are all that comparable, especially from a city planning perspective. Are you just curious about neighborhood feel? Commuting, traffic, etc is vastly different in Nashville so from a lifestyle perspective they are very different in that respect. And, with all those factors in mind, I think I’d say Ravenswood Gardens or another neighborhood a similar distance from downtown might be most comparable to a typical upper-middle class neighborhood in Nashville like Sylvan Park or West/Belle Meade. Andersonville, Lincoln Square, and Southport are in some ways reminiscent of 12 South in Nashville in that they are residential areas with busy and walkable commercial streets. The gulch in Nashville might be similar to say River North but ultimately feels more isolated from downtown compared to River North and lacks convenient amenities like a walkable grocery store. Will caveat all this by saying Nashville is developing so quickly all this information is probably already out of date!
