But that's only in the basis on the science side. Practically speaking if you compare them to DBZ. Accelerator can reflect back the hamehameha of the monkey guy or touma will just erase it entirely.
But their are certain limitations like for now. Accelerator is just half of the strength he has before. Even with 10+ clones to do his computation. That's only result into half of his powers before. Just show how monster his brains before damage. But still it doesn't change the facts about his ability to control vectors that he touches. With a limitations that its in the range of the computing capabilities and also within his time limit plus the range of signals.
But accelerators ability doesn't apply to magic which is the enery it's using is from an alienated world. Or just to say has its own principles. If the law that the magic state that it can't be block or redirected then it will hit.
As for touma........ if your a mage and an esper or any kind of being that relies on his power to do the trick...... TOUMA IS YOUR WORST NIGHTMARE
just snipe him down or use a cannon. And then his dead and also no close fight unless your practically saint class or above human strength but your make sure your not using power ups because its still useless. Like charge your body with energy. Its useless he will dispel it if you touch him or he touch you. Just make sure your own strength without anything can smash a boulders or building....or just master class of a martial arts but also be warned that his not easy to be taken down....... then you can win.
