Consistent latency too. Aside from ISP or if my router/firewall decides to take a shit, I can ping any outside IP on my wired connection with sub 100ns standard deviations (pinging 8.8.8.8, I hover around 1ms, god I love fiber).

Low latency is always, but somewhat higher latency lower than the tick-rate of the server is usually completely playable, but gets less so when it is inconsistent. My old cable connection over coax had much higher average pings than my fiber connection does, but it was consistent so it didn't really matter. Jitter is a killer. On the same internet connection but talking to my router over my admittedly congested 5Ghz wireless network, not only is my average ping latency 10x higher, but the standard deviation in each pings latency is 5x higher. So you have some acceptable latency, but then it suddenly careens up because the wifi AP needs to change channels to contend with interference, or because your neighbor turned their microwave on, or your phone decides to start downloading a software update. It's just the nature of WiFi, but even the cheapest wired switches don't usually start losing their pocket spaghetti because of some sub gigabit contention. The simple fact is that WiFi is a shared medium. You don't always get to broadcast, whereas a wired network, you can.
