But to try and stay on point: how do you measure the performance of a typical disciplined "system" (virtual) clock in a general purpose computer -- ideally without specialized hardware and software but those are okay if the results can be meaningfully generalized. Given those measures you can decide if you prefer NTP, Chrony, SNTP or something else.
You setup a high quality clock somewhere and pull timestamps from the general purpose computer you want to measure. Something like Nagios
This only works for measuring the ability to cope with time source that is an order or magnitude or so worse than your high quality source.
