That synchronizing to low statum NTP servers would be more exact is a myth. NTP is a peer-to-peer protocol, and makes good use of statistics, so it all depends on how many peers you have. Synchronizing with ten stratum five peers could possibly be even more exact than one stratum one.
Unfortunately, vendors of dirt cheap consumer equipment often only implements the trivial synchronization part of the protocol, properly called SNTP. This helps perpetuate the myths. NTP is one of the most well designed and yet misunderstood protocols. Perhaps that's food for an article in a future (please make it well researched and by somebody who actually knows what he/she's doing) issue of LWN?
