Compare Garling the try hard to a real badass with countless kills
Garling has to do some try hard racist rant to leave an impression on everyone. Of course, no one takes it seriously, since he didn't try going after the revolutionaries who actually attacked the Holy land and Fujitora who helped him free slaves. Garling is just over compensating for his objectively shit record and countless L's. Sommers on the other hand, doesn't need to say anything. His presence and record likely speaks for itself. There is of course, a trope/ or saying, that the quietest guy in the bar is the most dangerous.
