These are good points, but I'd like to add that unless someone is dealing with extreme latency (ie: > 150~200ms), jitter is typically a bigger problem. If you have a consistent latency of, say, 100ms, you can account for that. People adjust. They can plan for being a little slower to react. On the other hand, if you're playing a shooter and you're constantly bouncing from 20ms to 100ms, you're likely going to feel pretty unhappy. You'll be forced to constantly adjust for actions happening slightly too fast or too slow depending on the direction/severity of the jitter.
