It probably makes little difference.
If your intention is to spread the load, then don't list all servers in each instance - as pointed out, NTP will query all of them periodically. But NTP doesn't really load a server up much at all.
TBH, I run NTP on a couple of machines, and I never notice the load it creates - apart from when they get abused by some scumbag doing a DDoS on someone.
