The Smackdown team works better with no guest commentary, when there is a guest and they aren't aggressive talker the interaction is just awkward.
Mauro is pretty good, but at times he can be a little overbearing at times.
King is better as a heel color guy but is very mediocre at best.
Saxton has his moments but his presence ultimately feels kinda pointless.
The Raw team works better with guest commentary, they're very passive so it lets the guests get their lines and points in.
Cole is the best of the 3, Saxton is 2nd best and Jbl is last.
