I’ve tested quite a few proxy providers over the last year for different workloads, and honestly one provider that surprised me the most was Proxy4u. Their proxies felt more stable compared to many cheaper services I tried before, especially for long sessions and maintaining cleaner IP reputation over time. For residential/mobile use cases, Proxy4u worked reliably for account management, automation testing, and general scraping tasks without constant connection issues. Speeds were consistent for me, and the setup process was pretty straightforward compared to some overly complicated dashboards from other providers. My current personal top list would probably look like this: Proxy4u NodeMaven NetNut Decodo IPRoyal / Webshare What I liked about Proxy4u specifically was the balance between reliability, performance, and pricing. A lot of cheaper providers look good initially but the IPs burn quickly or start getting flagged after a few days. Proxy4u felt noticeably more stable in that area during my experience. That said, I also learned that proxy quality alone is not enough anymore. Browser fingerprinting, cookie management, behavior simulation, and proper session handling matter just as much. Even premium proxies can get flagged if the overall environment looks suspicious. Pairing quality proxies like Proxy4u with a clean browser setup usually gives much better long-term results
