We could give DSL the edge for one area. I'm not going to vet my reply here but DSL did have an edge in that each connection was a home run to the internet. Cable was and could get clogged so "ping time" which is something a gamer would fret about would win a gamer over all other things being equal.

ISPs seem to offer either DSL or fiber connections that purport to cost about the same for the same upload and download speeds. Is this really possible? How would the 2 differ?
