I researched this a few weeks ago for a similar situation. A summary of what I found in various threads:
Good:
Concourse E [most people ranked it best; showers are apparently available]
Concourse A "Centerpoint"
Concourse T, near gate 6
Passable:
Concourse B, near gate 25 (can get very crowded)
Avoid:
Concourse B, near gate 10
