Been messing around with both lately after a recent client ask. Honestly I always thought IPv4 was the way to go for scraping and stealth but tried some IPv6 for giggles. Price wise IPv6 is like half or less of IPv4 but the quality feels... eh, hit or miss. Some providers are great with native support, others I get errors or slow loads. IPv4 still smoother, but it costs a lot more. Curious if anyone found a good balance or got better CVRs with one over the other. Just started testing more, so any real-world tips appreciated.
