Gibbs is worse because he is an in-your-face liar and provocateur. Carney is just dumb and clueless and has the same personality as Obama’s teleprompter.

Mr Claire Shipman (Carney) is a more refined and polished liar - and therefore dangerous.
Gibbs is an ugly and detestable assh_le - who looks about 30 years older than he actually is. See also: baffoon.
