I’d say Carol has an advantage due to her energy beams while Diana usually has no long-range capabilities. If she can consistently block the beams with her bracelets though, it’s close quarter combat, where they would be about evenly matched, both being super strong and nigh indestructable. I’d give Diana a slight advantage then since she would probably manage to bind Carol with her lasso at some point, which is unbreakable. Also, come to think of it, Diana has super speed too, giving her another advantage from the start.

So yeah, Wonder Woman it is. DC’s heroes are ridiculously overpowered compared to Marvel’s.

Just imagine Quicksilver and Flash meeting:

QS: Oh, you’re a speedster too? I can ran faster than the speed of sound, how about you?

F: Well, I can run faster than time.

QS: Wtf?

F: Also, those two over there are also faster than you.
