Apgujeong/Banpo/Jamwon and Daechi/Dogok/Jamsil belong to different living spheres

Comparing them based on apartment market prices or transaction records is actually meaningless.
The cores are different, centered around Shinsegae Gangnam (Express Bus Terminal) versus Samseong-dong.
Previously, the center was the Apgujeong McDonald's Rodeo area, but as that faded and the Honam Line development began, the focus shifted toward the Express Bus Terminal.
The Apgujeong/Banpo/Jamwon area lacks office districts and instead has the Legal Town as its hinterland,
whereas Daechi-dong is flanked by the Teheran-ro commercial district and the entertainment facilities of Jamsil.
These two living spheres have recently become clustered and move as sets.
During the Park administration, the transaction prices of Daechi and Shinbanpo Hanshin were almost identical,
but now the gap between Daechi and Jamsil has narrowed significantly.
Their movement patterns are also quite different;
people in Apgujeong/Banpo/Jamwon mostly move North-South,
with relatively less East-West movement.
People who prefer moving North-South—
toward Gwanghwamun, City Hall, or Namsan,
or heading south via the Gyeongbu Expressway—
are likely to be concentrated in Apgujeong/Banpo/Jamwon.
The center is defined by Line 3, the Dongho Bridge railway bridge, and Hannam Bridge,
with Seongsu Bridge as the eastern boundary
and the Banpo Jamsu Bridge as the western boundary.
Originally, the residents who moved into Apgujeong/Banpo/Jamwon in the 1980s
did so because of the Line 3 corridor, which at the time ran from Gupabal to Yangjae.
They go to Gangnam St. Mary's Hospital and don't travel as far east as Asan Hospital.
Local clinics are plenty along Gangnam-daero in Apgujeong and Banpo,
and for libraries, they can just go to the National Library of Korea.
For department stores and malls, they go to Shinsegae Newcore;
there is no reason to go all the way to Lotte in Jamsil.
It is baffling to see people comparing prices or pitting Apgujeong/Banpo/Jamwon against Daechi/Dogok/Jamsil.
Daechi holds the symbolic status of a school district,
and it has Samseong-dong, Teheran-ro, Bongeunsa, and Seonjeongneung.
Furthermore, its sphere extends across Tancheon to Sincheon, Jamsil, and Seongnae.
