If you were to take the UZR splilts by face value, on average CFielder's did 3.05 UZR better at home.
Even if you were to adjust for park, no one ever came even remotely close to Gut's 2009 defensive season.
Gut was even better in Cleveland overall on a rate basis and his '10 season was worth 15+ runs by any other system either than UZR. I think hes the best defensive CF in baseball.
