Reo's Kabal would almost certainly be better than my Sub-Zero but we're not assigning character placings based on the skill of any two individuals, are we?
The matchup with Kabal is OK because you get rewarded properly for making the right reads against him. Jump the wakeup buzzsaw, free combo. Block the wakeup nomad dash, free combo. The worst case scenario is that you jump over the nomad dash releasing your pressure, but you definitely are rewarded handsomely for scoring untechable knockdowns on Kabal. You can check him with the iceball and once you corner him, he's dead because ex nomad dash is the only way out of the corner, and it's incredibly easy to bait that thing. Many people think Kabal has great wakeup, I think his wakeup game's his worst feature. It's pretty bad.
peckapowa, Raiden beats Sub-Zero pretty comfortably, in my opinion, too.
