In the Hyper-Darwinistic meritocracy that is Noxus, Swain is clearly the most fit to rule as he is the one who seized power. His conniving manipulation of political opponents and ambition sets him well apart from the likes of Darius, who doesn't care for politics, and the assassins are too narrow minded for ruling with any kind of power. I would say the only possible threats to Swain are Leblanc and Cassiopeia

Last I checked, Snake Lady is down in the sewers and LeBlanc is in Swain's pockets.
Swain probably Epitomizes the classic Noxian refrain of "strengh in all its forms." Better than anyone, which is what makes him so formidable.
Hes a brilliant battlefield tactician that leads from the front lines, earning the admiration and loyalty of the average noxian as well as the millitay higher ups like 
.
But hes also a skilled politcacian adept at backroom maneuvering and skulduggery, allowing him to hold his own among the noxian elite.
But hes also a scary bird mage with in depth knowledge of powerful magic, earning the loyalty of people like 
.
The man is capable of wielding multiple forms of power in unison, which makes him incredibly dangerous. Unfortunately, nobody knows exactly what Swain is up to, or what his end game might be. Which is pretty scary, he aspires to the most powerful throne in the world and nobody has any idea what hes going to do with it.
She basically had a tea party with Swain after they overthrew the last general and had a cute talk before Swain began discussing business.
...and Swain asked Leblanc that if she can substitute him with dueling the last general as well in the old lore. It is actually hillarious how the spectators commented "We did not know Swain was this OP". They must have seen Swain do a Leblanc QWE combo, WITH ONE OF SWAINS LEGS BROKEN. Surely somebody should have thought something was wrong lol
