I mean, at a minimum there's no travel time since you can have two fingers on the directions you wish to press, four even. You can be pressing the next input on the frame after you're hitting the previous. It's miles faster when you break it down in milliseconds. So there are a lot of techniques that can be performed faster. Most of the time that doesn't matter, you're getting the same result, but I think when when the right technique comes about, this becomes an issue. It just takes the right players to complain at a tourney, and then that device is banned.
Here's the layout that full schedule had retrospectively banned on MVC3
TOs said it was fine, but then players complained when they could see what he was doing with it.
In any case, as soon as you see people doing things with the hitbox that people can't do with regular sticks, and I do believe due to the rapidness of the presses it's very possible that this occurs (even with SOCD cleaning) we will see the whole controversy of hitbox controllers and their legality crop up again. And that's fundamentally, because they allow people do to things that everyone else can't do.
People often talk about Viper ball as a good example of something you can only do on a hitbox.
That's what Fullschedule was using them extra buttons for in Marvel.
I don't think using one is cheating or anything like that though, in fact I think they're kind of fun, but I do think they deviate from the design intentions and it's challenging to balance them in some scenarios because I do think they enable players to push beyond the theoretical limit of what a player is capable of on a traditional stick.
