I like having a decent upload speed, and I like the reduced latency. That all said, at this point I have no loyalty to Cable and will probably go back to DSL should opportunity present.
It's true the max upload speed of ADSL2+ is 1Mbit (128 KB/s) where as the cable plans are 2Mbit (256 KB/s) upload. If you aren't close to an exchange or cabinet then you would probably notice the difference otherwise I don't think it's a significant since usually people aren't uploading much at all.
Well I have just signed up for an online backup service and upload speed is pretty important to me. So TCL is still the best option for me in that respect.
