I don't know why this shocks people, The Tigers have a great team. They have a deep rotation which above average 2, 3 and 4 SP. The White Sox also are above average at the 2-3-4 spots. The Sox have a good bullpen, the Tigers do not. The Tigers have a great lineup, the Sox do not. The Tigers have an average defense, the White Sox are above average in most of the key spots.
The Tigers are built, if they perform, to win 100 or more games. The White Sox are built to win 85 and hope things go right.
As we found out last year, sometimes that works and sometimes it does not. Still have to play the year out.
