hej Slide,
I checked the site, and I think the first one (DW-G120AB) is a deluxe version, and it seems the only advantages are the power burning feature. Id say it doesnt differs much, but Im not sure what the power burning feature is.

Check this site out, it explains the
Buffer-Underrun protection. They both have that function, just an other version. Id say the deluxe version (120AB) is slightly better.
Hope I helped you,
Greetz,
