Centurion clubs, at least the one in DFW, do not have a true business area with mini cubicles like every UC I have been in. There is a conference room that one can book free of charge though.
If you plan to make lots of calls, the UC is better for you.
If you plan to eat/drink/shower the Centurion is better for you.
At any rate this new club will reduce crowding in both SFO UCs and the GFL.
