This is nothing new. I have used both SDSL and ADSL. The only difference is the modulation scheme. G.DMT versus G.LITE.
SDSL is symetrical which means the same speed in both directions. SDSL requires a dedicated copper pair between you and the Telco CO. ADSL rides over an existing 1B line. SDSL is typically used for Business accounts and at a premium.
More importantly is the number of hops and the amount of congestion between you and the TIER 1 of the internet. This is where most of the bottlenecking occurs. This is true regardless of the medium (DSL, Cable, Wireless).
Another big misnomer is that T1 is better than DSL. Well in many instances it is. But T1 only means that you can do 1.54 MBS bidirectional from you to the CO. Again, the pipe could be a DS3 but if there is congestion between you and TIER1 the big pipe does nothing. Also, most applications do not require a fast uplink speed, so regular DSL (512K x 128K) should do just fine. This can be demonstrated with a bandwidth monitor.
