di ko ata nagets TS...
sweeping is the technique, 'shredding' is the definition of a particular style of guitar playing.
if you want a comparison of different techniques used to play the same notes within a scale, then it's gonna be more like 'sweeping vs string skipping'
edit : to somehow answer the question...
i'm up for sweeping madness kasi ang ganda ng tunog for me. but i'm not a good sweep picker...
tapping na lang mga ser!
