Right - the popular sentiment on my smallish town Facebook group is people dropping their 300mbps cable since Spectrum is an awful company to deal with in favor of cell-based (T-mobile or Verizon) home service. 90%+ of people in most areas don't need internet any faster than Netflix requires, and nobody is running ethernet so WiFi speeds are going to be the limiting factor in internet speed for most everyone else.
I went from ~250Mbit to Gigabit recently. I don't notice it on my wireless clients at all, but it is really nice on my main PC, which is tied directly into the router via a good 'ole cable. I've seen actual downloads speeds flirting with 100MB/sec, which is really nice when downloading some of these massive 50GB+ games.
