The best SOCKS5 proxies pair a clean IP pool with a genuinely complete protocol implementation: UDP ASSOCIATE, username and password auth, IPv6 support and remote DNS.
Most vendors tick the first box and fail the second. A network with excellent residential IPs but TCP-only SOCKS5 is useless for gaming, DNS tooling or real-time media work.
Score candidates on pool quality for your targets, UDP support, auth flexibility, concurrent connection limits and documented endpoint stability. Test each with curl and a UDP client before committing.
Re-check annually — protocol support improves quietly and a vendor that lacked UDP last year may support it now.
