4. They are versatile
The Usos have proven that they are the most versatile tag team in the WWE whether it's as babyfaces, heels or tweeners. Their first run as babyfaces was arguably the tenure that had established The Usos in the Tag Team division.
But ever since they turned heel, it's clear that their characters evolved. And as their gimmicks had evolved, they had gotten themselves over with the WWE Universe again which led to another babyface turn following a rivalry with The New Day which even led to a Hell in a Cell match at Hell in a Cell 2017.

They have proven time and time again that they can be effective even when they have different alignments.
Fast forward to 2019, and The Usos are set to face Shane McMahon and The Miz for the Smackdown Tag Team Championships at the Elimination Chamber 2019 PPV event. This shows that they can go toe to toe with any tag team in the WWE regardless of what their alignment is, and they can still stay over with the WWE Universe.
