So, I've been testing these three providers for a while now and just stumbled onto a setup that actually works for high-volume scraping w/o getting flagged. Honestly, I was kind of stuck trying to figure out which one gives the best speed and anti-detection for residential proxies. Turns out, mixing BrightData with some Smartproxy rotators and a dash of Oxylabs for geo targeting gave me the best results. I was worried about latency and detection, but by splitting the load and managing the rotation manually, I saw a huge boost in success rate. The secret was in how I configured the sessions and keeping an eye on the session persistence. Still playing with the headers and user-agents, but this hybrid approach feels promising. Anyone else tried stacking these or have tips for fine-tuning for massive scraping jobs?
