Which smart home in Chengdu is better?

This question shows that you don't understand smart home yet, and I can't directly say who is better. This quality is based on price and system.

Wired systems-represented by KNX: contorl 4, Hedong, Luchuang, leax, Yongnuo, Crestron, Weimai, Esafe, Enoch, etc. Are highly integrated, very dazzling.

Wireless systems-there are several in China-such as Eurobo. And abroad-represented by Fibaro, but many of them are made in China, so we don't recommend you. The best way is to recommend wired, generally choose wireless. The stability requirement is high. If it is a villa, it is recommended to use a wired system.
