Briggs, Harris, Vasher, and McGowan (over Chris Harris) are better. Urlacher, Tillman, Ogunleye, and Alex Brown are at least as good. Mike Brown, the other DT (vs. Tank or Ian Scott), and Hillenmeyer are probably slightly worse. The backups (D. Manning, Idonije, Williams, Payne, Anderson) are better than the 05 backups which included Azumah, Mike Green, Todd Johnson, Boone, and Michael Haynes among others. I don't think it's a stretch to see this defense being better than the 05 version. Many of the players you mentioned are now older, with much more mileage on the tires, than they had in '05. I think there are alot of assumptions here that might not pan out.
