Anyone else think that McGonagall is underrated as a duelist?

She seems very underrated among Potterheads. Most don't even put her in their superiore, in alto 10 best duelers list, while characters such as Bellatrix are present in a lot. I've heard a lot of arguments about how she's "old" and probably can't fight as well as she used to, but Dumbledore is older and had the upper hand when dueling Voldemort at the Ministry of Magic. I personally think her only superiors are Dumbledore and Voldemort.
