Is Mihawk a better swordsman than Oden?
From the info given so far, and from a narrative POV, it seems unlikely that Oden was stronger than Mihawk back then. Mihawk being able to cut through the tough skin of a Yonko and injure them seems like a reasonable claim now. It also makes having Yoru and making a blade black seem like a bigger deal.
Who killed Oden?
Kaidou 96 Chapter 972 (p. 16-17) and Episode 974, Oden is executed by Kaidou.
Is Oden a yonko level?
Oden could be the weakest Yonko for all I know, but theres way too many signals being thrown about him to interpret anything other than him being comparable to them. Very strong but probably not quite Yonko level. Probably like just below or on the same level as Mihawk for power-scaling.
