The quality of service will depend on your provider. Some are better than
others. This applies to both cable and DSL. DSL also often has the
potential problems of dealing with different companies for the cable pair
and DSL service and the resulting finger pointing. Also, the amount of
sharing also depends on your ISP. In the case of my cable access, the
subnet mask is 255.255.255.0. This means that the DOCSIS channel is shared
by less than 255 subscribers. On the otherhand, an ADSL system I was
working on recently, two DS3s (2x 45 Mb/s) are shared by 448 lines.
So, all in all, you simply can't say cable or DSL is better, even though
your personal experiences may say one or the other is superior.
