At&t dsl vs Charter cable?

I need help deciding which service to get I have Charter cable internet currently my speed is 10mbps. At%26amp;t dsl offers a max speed of 6mbps in my area. I want the best service for online gaming. My current internet speed test is 100mi away and is 49ms with cable would this be lower with dsl?|||cable (co-ax) is generally faster than DSL which is using telephone copper cables, and your restricted by the characteristics in the telephone line and distance from your local telephone exchange ( 7 Km radius) and the condition of the pairs, they may have faults in sections of cable that is ok for voice, but may cause drop offs when connected to ADSL? IF you go down the DSL path make sure the run an error data package from your telephone line to check error rate, and if it is within specs for the service, difference between guarantee and offer? You will never get maximum speed anyway, for the above reasons.
