Contrary to TOR wankers er, popular belief, there have not been any omniscient sources to confirm that Vitiate is more powerful than any Sith preceding him. Even if we consider the TOR encyclopedia to be third person omniscient, being more powerful does not mean that you are a deadlier overall combatant, and so there is still room to debate the issue.
Valkorion takes credit for many feats that demonstrate a potent understanding of various dark side rituals and sorcery, but his actual combative demonstrations are scarce, and those which exist are almost always on some sort of Force nexus. He has easily beaten a strike team of four featless Jedi, and has one-shotted some marginally powerful characters like Darth Marr, but that's about it. What has he actually done off-nexus that makes people think him to be so deadly as a combatant? Indeed, his performance in the Revan novel, although before his prime, elucidates just how awful of a fighter he is, getting disarmed by a saber throw from the Exile that allegedly would've killed him had she aimed for his body, getting knocked on his ass by Revan, etc. This is hardly surprising; Valkorion has pretty much no experience having to actually fight people who are on remote parity with him, and when he does, he usually loses.
Did I mention he was scared of Freedon Nadd, who Exar Kun is far more powerful than?
Exar Kun, meanwhile, is able to put Luke into a coma, and he does this as a spirit - which, as confirmed by the author, is weaker than his flesh form even when taking into account Yavin's nexus. He also has the aid of Kyp, but it's stated that Exar is only able to access "some" of his powers with him, and Kyp himself notes that his Force abilities with respect to sensing are feeble compared to Exar's, so the evidence points towards full power Exar > spirit Exar + Kyp. He also does this right after having helped Kyp lift the sun crusher out of the gravity well of a gas giant, which is stated to have tired him. This is a later version of the Luke, mind you, who defeats the reborn Emperor in a lightsaber duel. On their first encounter, the reborn Palpatine comments that Luke could give him a tough fight [albeit lose].
This alone is a far greater combat feat than anything Valkorion has ever done, given that he relies heavily on everyone else being far weaker than him, along with prep, rituals and nexuses.
Let's say you think that Valkorion is more powerful in the Force than Exar Kun is. That doesn't mean he would win a fight. The disparity between the two in dueling prowess means that Valkorion needs to be so much more powerful than Exar that he can ragdoll him outright. Given that it's implied that Murr > Vader, and Exar is explicitly stronger than prior ancient Sith, Valkorion would have to be capable of ragdolling a Vader tier enemy. Yoda, who is on par with Sidious, who is explicitly stronger than Valkorion, cannot ragdoll Dooku, who is weaker than Vader. There's no reason to believe that Valkorion can do that to Exar, just because he can one-shot weaklings like Darth Marr when he's distracted fighting his guards.
Tipping the battle in Exar's favor, Ulic is vastly more powerful than Arcann, given that he was able to stalemate an Exar not far from his prime, while Arcann got one-shotted by Valkorion. Seeing as how Yoda couldn't one-shot Dooku and Yoda ~ Sidious > Valkorion, Arcann must be significantly weaker than Dooku, potentially weaker than Savage or Ventress.
The two together easily crush Valkorion and take the majority against the boss.
