I’ve tested all major proxy types over time, and the results really depend on the target site. For general scraping, residential proxies still perform best — fewer bans and smoother rotation.
If you’re collecting large datasets or running multiple threads, ISP proxies are a solid middle ground since they’re faster and still look legit to most websites. Datacenter proxies can work too, but they often get flagged quickly on sites with strict anti-bot measures.
Overall, a mix of residential and ISP proxies usually gives the best balance between cost and success rate.
