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.
Aldebaran is approximately 2.5 times brighter than Betelgeuse when comparing their apparent magnitudes. Aldebaran has an apparent magnitude of about +0.85, while Betelgeuse has an apparent magnitude of around +0.58. This means that Aldebaran appears less luminous in the night sky compared to Betelgeuse, despite being a significant star in its own right. However, in terms of intrinsic brightness, Betelgeuse is actually much more luminous than Aldebaran, being a red supergiant star.

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.
Betelgeuse is approximately 100,000 times brighter than Aldebaran. This significant difference in brightness is primarily due to Betelgeuse's status as a red supergiant star, which has a much higher luminosity compared to Aldebaran, a red giant star. Factors such as size and temperature contribute to this disparity in their brightness as seen from Earth.
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".
