Rigel is brighter.
Generally, true, but there are rare exceptions. For example, Betelgeuse is "Alpha Orionis" while Rigel, generally brighter then Betelgeuse, is "Beta Orionis". Betelgeuse is a somewhat variable star, and when the Bayer designations were assigned, Betelgeuse was the brighter star.
Betelgeuse 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.

Rigel is the bRightest but sometimes Betelgeuse is brighter
Betelgeuse is a red supergiant star and the Rigel is a blue supergiant. Both are in the same constellation Orion
Usually, the beta star. Stars are given names based on the constellation that they are in, with the brightest star in the constellation being "Alpha", the second brightest being "Beta, and the third-brightest being "Gamma" - and so on through the rest of the Greek alphabet. However, stars _can_ change their brightness. In the constellation Orion, the red supergiant star Betelgeuse was, in the 1600's when the stars were cataloged, the brightest star in Orion. So Betelgeuse was listed as "Alpha Orionis", while Rigel, a close second, was listed as "Beta Orionis". But Betelgeuse has been slimming down, perhaps beginning the collapse which will result in its destruction as a supernova. At any rate, Rigel is generally brighter than Betelgeuse this century. Not always; Betelgeuse is a variable star, and at its brightest, it is still brighter than Rigel.
Rigel is blue and Betelgeuse is red.
