The two types of proxies are useful in their own way, for example, resident ones work as buffers and conceal the IP address, keeping you anonymous online, while data center proxies refer to IP that is not tied to a specific home host and are placed in data centers, and as you can understand they are also used to provide anonymity on the web and provide access to restricted content. By the way, if necessary, you can buy both reside proxy as well as data center proxies from ProxyEmpire provider https://gologin.com/best-proxy-server-services/proxyempire.
