I'm taking a vortex all day because it is continuous. Like for example, compare Evil ryu to Akuma (before deleayed wakeup but akuma can still mix people up tho). Evil Ryu could easily land one combo and take about 35 percent to 40 percent and drain a lot of health just like that. Akuma however could just land something as simple as a sweep and mix you up multiple times. It is very scary when someone can put you in the same position and you have to guess right or keep losing health. Batgirl is like that, and if you were watching sonicfox at summer jam, he utilized multiple things that make her vortex from a 50/50 to like a 16/16/16 etc. So in conclusion, vortex for the win always. Damage is good, but vortexes are king in fighting games.
Edit: Batgirl can actually zone some characters (unlike flash), she has a teleport which blows up interactables and anti airs, more rewarding wakeups, etc. If flash had a teleport and some kind of zoning, I'd put him above her, but he doesn't.
