I might get tomatoes thrown at my head for this, but I don't care. Ken is a better host of Jeopardy! than Alex Trebek was. The way he responds to the player anecdotes, knows when to inject a touch of humor into correct response confirmations, and his history on their side of the lecterns means he has a relatability to the players that Trebek could never have. He knows how to treat the players with respect when they've earned it, empathy if they're struggling, and admiration for a tough answer or a winning streak, and his banter with the players is miles and miles better than Trebek's was. Unlike Alex, he doesn't throw on a haughty accent for every European related category, he doesn't deride the players with snark or sarcasm for a wrong response, and he doesn't give the "Bless your heart" smirk and a verbal "aww good for you" response to the players anecdotes. My biggest complaint of Trebek was always how he kept this air of superiority over the players. I'll give you that Ken doesn't have the most perfect speaking voice, and he's got a slight lisp, but he just embodies everything about Jeopardy! and he should be THE singular host of ALL things Jeopardy! for the foreseeable future IMO.
