SKT Winning Worlds
Worlds 2017 Knockout Stage
SKT will not have to face either LongZhu or Samsung and will only meet them in the finals. (Assuming they aren't both disqualified) SKT will almost certainly win against Misfits, and only needs to get past RNG and one of the others in the finals. LongZhu won against SKT in LCK because of the game plan that focuses Huni, and SKT will have some countermeasure prepared by kkoma. Khan and PrAY are good players, but they aren't that much better that Faker and Peanut, so it would pretty much depend on the draft and would depend on how long SKT can stall from LongZhu's early game. Samsung Galaxy made it into game 5 against SKT in 2016 worlds partially because of the Braum Sejuani combo, but that was a pocket pick from Samsung. Samsung have been a good team, but SKT know what Samsung can do compared to RNG as they have faced against them many times. RNG is the only main obstacle blocking SKT, but they have better odds (history repeats itself), and the finals would be won against any Korean team.
The only one who can stop SKT now are RNG and LongZhu, but LongZhu aren't used to the pressure of being in worlds finals compared to SKT, and so SKT has the upper hand.
Huni < Khan (Khan wins by a lot) Peanut > Cuzz Faker = BDD but faker has more experience so Faker wins but not by a lot PrAY > Bang GorillA and Wolf IDK, wolf has some great plays but GorillA can do the same so idk who's better depends on adc
