Favorite Host - Phil Keoghan. Also included are Gordon Ramsay and Julie Chen.
Least Favorite - Jeff Probst (I used to like him), Heidi Klum, and Padma Lakshmi (I like her but she just isn't that good a host imo) are a few.
Favorite Judge - Like all three current AGT judges (although with Piers it kind of sways sometimes), David Hasselhoff from the past, as well as a couple on other shows. Namely Tom Colicchio and Nigel Barker (based on only the first three ANTMs)
Least Favorite Judge - Not really a fan of the Project Runway judges and I hate Janice Dickinson!
