#4. The New Day

We know that they count as three superstars, but because we view The New Day as a singular unit, we'll group them. They've now been together for over 5 years now, the longest of any faction or group in WWE history.
With multiple Tag Team Championships to their name, they can already make a case for being the greatest tag team of all time in WWE and it's been nearly three years now since they've moved to SmackDown.

While they were in RAW after the initial WWE Draft in 2016, they've established themselves as a SmackDown team and it's the brand where they had their all-time classic rivalry with The Usos, multiple great matches against top teams, and most importantly - Kofi Kingston's rise and WWE Championship win.
It's hard to imagine the trio outside SmackDown and even if there's a need for a change, they're going to be together. We can't see a time in the near future where The New Day isn't together. They should stay on SmackDown for the rest of their careers.
