I Absolutely agree lol
But, they both are meant to fulfill similar functions, and they both achieve the same goal, which is to make noise lol
I think the rumble rig is more polyvalent; it can sound many different shades of good
And even though the YBA still has pretty customizable EQ, I think it's geared more towards achieving one really, really good sound instead of being able to do it all. In other words, it's good to have both
