The main difference people usually mention is not about raw performance, but about behavior under real conditions. Mobile traffic tends to fluctuate more naturally, which makes it closer to how real users actually interact online. That’s why [mobile proxies](https://www.simplynode.io/product/mobile-proxies) are often discussed in contexts where realism matters more than consistency in a strict technical sense. Instead of staying perfectly uniform, the behavior shifts depending on network conditions, which can actually be useful in testing environments where natural variation is expected rather than avoided.
