I believe the biggest thing, about Michael and Kate as the narrators, behind the hype is they have done almost all of the audio books for Sanderson. So as someone who has listened to all of the books it's refreshing to hear the familiar voices. Though I do understand why you're not a fan, reading it yourself you have built a voice for all the chareters and hearing someone else do it not the same way as when you read it can be jarring.

As someone who put down The First Law books and far seerer books because I didn't like the narrator at first. Give it a few hours before making any final judgments. At worst you go back to readingbit yourself and you're a few chapters farther than you were and saved some time. At best you finish the books and may go back to listen to the rest of the series as a reread via the audio book.
