Theres more to DNS then just latency to the server and time it takes to give a resolution. Its also how often they update their logs, if they use blacklists, how many servers they have, server dependability, etc. Not saying that program isn't good(actually I quite like it) but to be honest, unless you have knowledge of how a DNS server works, or your troubleshooting a problem, I say just leave it to your ISP's DNS. Its like firmware, I think some people get the "I dudditz" attitude and think if its new, they want it and it will make everything better. JMHO.
