What is the brightest constellation in the whole day? What is the constellation with the most stars?

The brightest star in the sky is Sirius Canis, but if which constellation is the brightest, I personally think it should be Orion. Before this whole day, Orion, the 50 bright stars, occupied most of them. As for which constellation has the most stars, it is difficult to answer, because there are many known and unknown stars in any direction, even galaxies outside the river, so I think if we have to delve into which constellation has the most stars, we can only calculate it according to the area of the constellation. The largest constellation is Ophiuchus, with an area of about 1300 square degrees, followed by Virgo.
