Been messing with proxy rotation scripts lately and honestly picking a provider is a nightmare but so important. I've tried a bunch so here's my quick take. BrightData is solid for quality but prices are crazy and their ips get flagged more now. Smartproxy is ok middle ground, faster setup decent pools but their residential stuff can be sus with speed and location. Oxylabs is premium reliable but way overpriced for most people. Cheap generic ones work for small tasks but if you're scraping heavy or need anti-detection they'll burn out fast or get you banned. For python rotation i just use requests and rotating proxies list but gotta be smart about switching IPs especially for high volume scraping or login stuff. Do you all use one provider or mix them up? Or some secret sauce i haven't tried yet?
