This is difficult to judge independently, because I know that super critical @Op.123 considers Saioa Hernandez the lesser evil among contemporary singers. So I naturally think of why she might be better. The beginning of the aria and the chest voice shows a real great contrast, which I would have noticed also without this bias. In those dark parts of the aria, Hernandez is really impressive, maybe captivated me even more than the singers of good ole times. However, as the aria progresses, I notice something unpleasant in the higher notes, which I do not have the name for. There I prefer Gheorghiu, the voice is thinner but does not do that thing. Was Hernandez in her prime here ? I will vote for her due to that spectacular beginning.
