She is still always stronger than her opponent. When Arcueid fought against Ciel in Ciel's route, their power was equal(Arcueid was still pretty weakened here, otherwise she would have easily defeated her) but after a while Ciel got tired and Arcueid defeated her because she couldn't keep up. That's what I mean with infinite power, she never gets tired and she can use as much power as she wants, she is like a Servant with infinite mana. Saber cannot use three Excalibur blasts one after another, but if Arcueid is wielding that weapon she can do it just fine. Her power is pretty much invincible, there are only a few characters in Type-Moon she has bad affinity with(excluding the Types, of course).
