I recently got a 1Gbit fiber and I have been very happy with it. I do not know if I am a heavy internet user but I have DisneyPlus, Netflix, HBO, Prime. I game and those games use a lot of data (80GB is normal now). I don't pirate stuff. I work from home 95% of the time. I do not see ANY reason to go faster. If I download a game and it is large I have to tell steam to cap the speed to 200 Mbit otherwise my machine freezes (I download games to a normal SATA drive and the machine is a Ryzen 9 9900X). I have to option to go to 2Gbit or even 8Gbit but I don't want to buy more expensive switches/routers and network cards for my computers.
Who (not including geeks) would want to go faster than 1Gbit?
