yo i asked about this before but need a fresh take. been using residential and datacenter proxies but now i'm eyeing ISP ones. they're supposed to be stealthier but i need actual numbers not just talk. some companies swear their ISP proxies hit like 85% success against anti-bot stuff but others are barely scraping 60%. checked out a few like ProxyRack and Bright Data they both claim reliability but the pricing and speeds are all over the place. some mention 100-150 ms ping and okay uptime but then you hear they choke when things get busy. anyone run tests recently? what's your real world experience with ISP vs residential or datacenter? looking for a decent mix of speed stability and not getting flagged. hit me with the facts gotta decide quick.
