GoodHonestly, I’ve tried all three proxy types depending on the scraping job I was working on. For big projects where I needed speed and didn’t really care about being detected, data center proxies always won out since they’re cheap and super fast. When I ran into stricter sites or needed better location targeting, I’d switch to knowresidential proxies, but yeah, those can eat up your budget quick. ISP proxies were kind of a sweet spot for some e-commerce tracking tasks, faster than residential and didn’t get blocked as much as data center ones, at least in my experience.
If you’re planning for anything long-term or at scale, I suggest looking into tools and services that support integration with proxies and make all the setup easier. I picked up a lot of tricks for this kind of thing from reading about web data extraction approaches on https://crawlbase.com/.
