When choosing a proxy service, I usually look at connection stability, available locations, supported proxy types, speed, and how easy it is to manage IP addresses. For regular work, a reliable paid proxy service can be more practical because it usually offers better control over geolocation, dedicated options, and compatibility with browsers or automated tools. I also check whether the provider supports residential, mobile, datacenter, or static proxies, since different tasks may require different connections. Clear setup instructions and useful testing tools are important as well.
