I agree with Curbo, Death and Joker. I remember back when people said Reptile beats Cage 7-3 or 6-4. Back then I didn't really agree with it and I still don't at best, Reptile can zone Cage out when he gets a good health lead. But besides that, in my experience Reptile gets raped once Cage is near him. I believe Reptile can dash out of strings, but that's not a guarantee and in most cases I end up getting blown up for trying it.
I think it is either 5-5 or Cage advantage. While Reptile might avoid some of Cage's pressure, it's not to the point that Reptile gets out of pressure for free. And once he does get out it's not like Cage has an extremely tough time getting in.
Also, my Reptile playstyle is very aggressive. I like to play footsies and pressure hard once I am confident. I do zone, but it's not my go to strategy. The most zoning I do is to chip away at health/build meter. Most of the time I throw forceballs just to get my footsies and pressure going. I also am an avid user of invisibilty.
