Sweeping can play roles in setting up Tech Bursts where the opponent is in a situation where they can burst out of a combo due to Undizzy or IPS but due to them being sweeped their ground tech input will be counted as a burst input instead resulting in a free burst bait.
This isn't the case from sweeps.
That exists for air hits that knockdown and allow techs like Parasouls jHP and Filia's jHK.
"Sweep all Solo Big Bands who play online. You know they just want to use Brass Knuckles, so just sweep em everytime you feel they are going to reversal a Brass."
Just curious, where is this quote from? o.O

I wouldn't recommend sweeping Band.
SSJ has 2F start up so it is difficult to time a sweep on it, and if you're wrong you get hit by counter hit SSJ which is brutal damage.
If you're on point with your timing then all you get is a soft knockdown and he gets to tech away / towards you.
Most Big Bands will do reversal DP which beats sweep or SSJ which is 2F start up and hard to time, compared to the long start up of H Brass which tends to get its armour shredded.
Also, other things that shatter armour in case you are curious include:
Double's Cilia Slide
Robo-Fortune's Mine
Fortune's Cat Slide
Valentine's Counter
and ANY hitgrab, which are moves that when they make contact with the opponent and are not blocked, apply a grab which shatters armour.
