Re: leaps and bounds better than the supposed 1Gbps connection
You don't have a Gbps fiber connection and you've never experienced it.
I have a proper FTTP Gbps connection now, and I can guarantee that there is nothing better.
That said, I had to wait a year using 4G, so maybe I'm a bit over-enthusiastic about it, but I did spend over a decade on a 12Mbps ADSL line, so I do know that there one hell of a difference.
