Obi wan clears. He beat maul twice if you include the fight on tatooine in rebels,he stood toe to toe with anakin and bested him, who in the same movie beat one of the best light sabre duelists in star wars count dooku. In attack of the clones fought jango fett, has fought general grievous and won, the choreography from the prequels is superior to that of the new films and the actors themselves performed said fight scenes as shown in behind the scene footage. Rey and kylo lose big time. and snoke is featless unless there is something in the new books that say other wise. As for the praetorian guard they stood and waited to be beaten by Rey and kylo whose skills are nowhere near the level of the sith or jedi from the prequels.
