Sirius appears brighter than Pollux because it is closer to Earth and is a more luminous star. Sirius is also a hot, blue star compared to Pollux, which is a cooler, orange giant star, further contributing to the difference in brightness.
It's a close call, but Pollux is brighter. Pollux has an apparent magnitude of 1.15 whereas Castor has an apparent magnitude of 1.96.(Note: the smaller the apparent magnitude the brighter it is)
The star Deneb is a blue-white star with a surface temperature of 8500 degrees Kelvin.
The apparent magnitude of Deneb is +1.25, a fairly bright bright star from Earth.
Deneb is a bright blue-white star in the constellation Cygnus.

This is the order from smallest stars to the biggest stars: Alpha Centauri, Procyon, Vega, Pollux, Polaris, and Deneb. These are the size(diameter) of them; though the size of the stars are not 100% accurate so they are likely to be predicted. Alpha Centauri is 1,527,000 Procyon is 2,652,000 Vega is 3,827,000 Pollux is 11,617,000 Polaris is 44,217,000 and Deneb is 203,000,000

deneb
The star Deneb is a blue-white star with a surface temperature of 8500 degrees Kelvin.
Deneb is a star. The word "terrain" is not applicable to stars.
The apparent magnitude of Deneb is +1.25, a fairly bright bright star from Earth.
Deneb is a bright blue-white star in the constellation Cygnus.
The Pollux Star is located in the Beta Geminorum
Deneb is an Arabic word and it means "tail". That's why Deneb is the brightest star in the tail of Cygnus the Swan. The bright star in the tail of Leo the Lion is Denebola.
The surface temperature of the Pollux star is 4,500 K
