Who has the better internet, cable, and phone package? AT&T or Comcast (People from CHICAGO only PLEASE!!!)?

So, AT&T and Comcast both have pretty much the same $99 dollar /month bundle. Who's works better and are there any hidden fees for either that I should be worried about? Like, after 6 month does the price skyrocket or something. I would really appreciate honest answers from Chicagoians! Thanks in advance!!!
