Wuhu is generally considered better than Haimen due to its stronger economic performance, higher GDP, and more developed infrastructure. According to the latest data, Wuhu's GDP per capita is significantly higher than Haimen's, indicating a more prosperous and developed economy. Additionally, Wuhu has better transportation links and a more diverse industrial base, which contributes to its overall appeal and potential for growth.

Wuhu's economic strength is evident in its GDP per capita, which was reported to be approximately $20,000 in 2020, compared to Haimen's $15,000. This difference can be attributed to Wuhu's strategic location in the Yangtze River Delta region, which has facilitated its integration into the country's economic powerhouse. The city has also been successful in attracting foreign investment and fostering innovation, which has further boosted its economic growth.

In terms of infrastructure, Wuhu boasts a well-developed transportation network, including a high-speed railway station, an international airport, and a comprehensive road system. This has made the city more accessible and has attracted businesses and tourists alike. Haimen, while having some infrastructure advantages, does not match Wuhu's level of development in this area.

Furthermore, Wuhu has a more diverse industrial base, with strengths in sectors such as automotive, electronics, and pharmaceuticals. This diversity has helped the city to weather economic downturns and has provided a stable foundation for continued growth. Haimen, on the other hand, is more focused on traditional industries such as textiles and shipbuilding, which may limit its potential for future development.

In conclusion, Wuhu is the better choice when comparing the two cities. Its stronger economic performance, higher GDP per capita, and more developed infrastructure make it a more attractive destination for businesses, investors, and residents. While Haimen has its own strengths, Wuhu's overall development and potential for growth give it the edge in this comparison.
