In my experience, stability and predictability are key when it comes to choosing between residential and mobile proxies. Static residential proxies are generally the way to go for long-term accounts that require a consistent IP address, as they tend to present a more normal home-like connection. Mobile proxies, on the other hand, are better suited for high-performance applications or multi-account setups where automation is involved. It's also worth noting that having control over IP rotation is crucial when using mobile proxies, as random carrier-side changes can indeed wreck stability. By controlling the rotation logic, you can make mobile proxies work effectively, but it's a more complex setup compared to static residential proxies. Static residential proxies are usually the safer choice for accounts that require a long warm-up period, as they provide a consistent IP address and are less likely to attract suspicion.
