Rigel is brighter than Betelgeuse.
Rigel is brighter.
Betelgeuse has an apparent magnitude of 0.42(v) and an absolute magnitude of -6.02. Rigel has an apparent magnitude of 0.12 and an absolute magnitude of -7.04. So Rigel is brighter.
Even though Betelgeuse is much larger, Rigel is brighter due to its much higher temperature. Rigel is about 11,000 K and Betelgeuse is only about 3,500 K.
Betelgeuse is brighter.
No, Rigel is hotter. Rigel is a blue star with a temperature of about 11,000 K, and Betelgeuse is a red star with a temperature of about 3,500 K.

Betelgeuse is a red supergiant star and the Rigel is a blue supergiant. Both are in the same constellation Orion
It isn't the brightest star - at least, usually Rigel is brighter. However, Betelgeuse is variable, and can sometimes be brighter than Rigel. Wikipedia lists its luminosity as 105,000 times the luminosity of our Sun; and the distance, as 640 light years. Assuming these numbers, this would make it as bright as a star that is 10.5 times as bright as our Sun, at a distance of only 6.4 light years. In other words, the extreme luminosity compensates for its distance.
