At some point in my life, I was forced to use 7/0.7 Mbps ADSL after having 50/50 Mbps and that ADSL was very oversubscribed (high packet loss and huge speed drops to <2 Mbps during weekends or evenings). Later on, I had FTTH, but I couldn't control the router (fibre was terminating at the landlord's house, and I had cat5e from the router to the place where I lived, and the landlord kept the router in the worst place possible so it was overheating during the summer).

Since then, I have tried to be in control of network hardware, and I now avoid *DSL, even though VDSL is decent nowadays. But the reason for 25 Gbps for me is "just because", as ISP charges the same monthly amount as I pay now (there is a setup fee for 25, though).
