This could be considered a trick question. Generally, Betelgeuse is brighter BUT Betelgeuse is what we call a variable star and there are times when it is fainter than Aldebaran.
Betelgeuse is brighter.
Betelgeuse is bigger than Aldebaran. Betelgeuse is a red supergiant star, while Aldebaran is an orange giant star. Betelgeuse is one of the largest stars known, with a diameter around 1,000 times larger than the Sun.
Betelgeuse is the brighter star compared to Aldebaran. It is a red supergiant star in the constellation Orion and is one of the brightest stars visible in the night sky. Aldebaran is an orange giant star in the constellation Taurus and is not as bright as Betelgeuse.
Betelgeuse is generally brighter than Aldebaran. Betelgeuse, a red supergiant in the constellation Orion, has an apparent magnitude of about 0.42, while Aldebaran, a red giant in the constellation Taurus, has an apparent magnitude of around 0.87. This makes Betelgeuse one of the brightest stars in the night sky, easily outshining Aldebaran. However, both stars are prominent and notable in their respective constellations.

Betelgeuse and Aldebaran are red stars.
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.
No, there are many other red giant stars in the Universe. Betelgeuse and Aldebaran are well-known red giants because they are bright and easily visible from Earth, but there are numerous others that exist both within our own galaxy and beyond.
The stars that are like supergiants are called "red giants" or "red supergiants".
The biggest and brightest stars are called supergiants. These stars are much larger, hotter, and more luminous than our Sun. Examples of supergiants include Betelgeuse and Rigel in the constellation Orion.
Aldebaran has a higher luminosity and a lower surface temperature than the Sun. Rigel has a higher luminosity but a higher surface temperature than the Sun. Bernard's Star and Alpha Centauri have lower luminosity and higher surface temperatures compared to the Sun.
Examples of red stars include Betelgeuse in the constellation Orion, Antares in the constellation Scorpius, and Arcturus in the constellation Bootes. These stars appear red due to their lower surface temperatures compared to hotter, blue stars.
