Which city is better, Jiangyin or Changzhou?

Jiangyin is good. Changzhou, as a prefecture-level city, was originally good, but it was delayed after the merger of Jintan. Jiangyin is the Wu dialect area of Su-Xi-Chang, and Jintan is the only area of Su-Xi-Chang facing North Jiangsu. Jiangyin and Jintan were both slaughtered in the Qing Dynasty, but it was Jiangnan people from Suzhou, Wuxi and Changzhou who moved to Jiangyin, so the Wu dialect in Jiangyin urban and rural areas was preserved. Similarly, a large number of immigrants from Huai-speaking areas in northern Jiangsu moved to Jintan, so at least 50% of Jintan people can only speak Subei dialect. The population of Jintan accounts for 1 1% of Changzhou. Jintan is the only area where Suzhou-Wuxi-Changzhou has been transformed into northern Jiangsu, and Jiangyin is the Wu dialect area of Suzhou-Wuxi-Changzhou.
