There isn't really a 'best' Pokemon in OU.

This is true.
According to the Smogon viability thread, Toxepex and Clefable are the most viable Pokemon in OU.
Here are Smogon's sets for each:
Clefable:
Clefable @ Leftovers / Choice Scarf / Sticky Barb
Ability: Magic Guard
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
- Moonblast
- Soft-Boiled
- Stealth Rock / Wish
- Knock Off / Trick / Thunder Wave
Don't run the Choice Scarf, in my opinion.
Thanks to its extremely wide movepool, Clefable can provide teams with many forms of utility, be it setting up Stealth Rock, crippling foes, or supporting teammates. Its ability makes it a reliable status absorber and as such a solid switch-in to Pokemon like Toxapex and Mandibuzz, while its typing makes it a decent check to Urshifu-S as well. Clefable can fit on pretty much any team archetype apart from hyper offense, but it most commonly finds itself on balance teams looking for the utility it provides. Clefable synergizes nicely with Pokemon like Corviknight and Mandibuzz that can check Pokemon such as Excadrill.
Clefable @ Life Orb / Leftovers
Ability: Magic Guard
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
- Calm Mind
- Moonblast
- Soft-Boiled
- Flamethrower / Thunder
Eh.
Calm Mind Clefable trades utility for the ability to be a potential late-game sweeper. Once given the opportunity to set up, it can often tear through teams. It mostly finds itself on balance teams, but it can fit on bulky offensive teams as well. It most appreciates partners that are able to gradually wear down the opposing team through entry hazards or status, such as Toxapex and Skarmory, setting it up to sweep late-game.
Clefable @ Leftovers
Ability: Magic Guard
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
- Teleport
- Moonblast
- Wish
- Protect
My favorite Clefable set.
Teleport Clefable goes all-in on reliable Wish passing, since Teleport allows it to bring in a teammate safely. It is most commonly seen on balance and bulky offensive teams that have members that lack but desire reliable recovery, such as Ferrothorn, Kommo-o, and Rhyperior. Wallbreakers like Urshifu-S and Hydreigon also enjoy Clefable's Wish support and ability to bring them in safely with Teleport.
Toxapex:
Toxapex @ Rocky Helmet / Black Sludge
Ability: Regenerator
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
- Scald
- Recover
- Haze
- Knock Off / Baneful Bunker / Toxic
Toxapex is one of the best defensive checks to Pokemon such as Volcarona and Calm Mind Clefable, and it can pivot into Pokemon like Urshifu-S comfortably thanks to Regenerator combined with its good bulk. Toxapex is most commonly seen on balance teams but can easily fit onto bulky offensive teams, as it doesn't let up momentum easily. Toxapex pairs very well with Pokemon such as Mandibuzz and Clefable to keep Urshifu-S in check.
Note: I take no credit for these sets.
Hope this helps! :)
