I think Shi is just a good journalist and does his job well, does his homework and writes pieces people can read with facts & quotes to back up his thoughts. He's practically the winner by default though.
With Davis, I feel like he'e never played an inning of his baseball in his life and asks borderline idiotic questions like "What does that stolen base mean to you?". Wilner probably has the toughest job of any of them having to talk to hockey fans after a Jays game and answer daily questions like "Why didn't Navarro just bunt with the tying run at first and 1 out? Instead he grounded in to a double play to end the game. Thanks for taking my call."
