Image Quality and Performance
When it comes to image quality, the Canon RF70-200mm excels with its bright f/2.8 aperture and high image quality throughout its zoom range. This lens is particularly well-suited for low-light conditions and offers optical image stabilization with up to 5 stops of shake correction.

However, it has a maximum aperture of f/5-6.7, which is less capable in dim lighting compared to the Canon lens. Therefore, photographers focusing on low-light performance may prefer the Canon.
Build Quality and Design
The Canon RF70-200mm is both compact and lightweight, making it an excellent option for travel and outdoor photography. Its dust- and weather-resistant construction adds to its durability. On the other hand, the Tamron 150-500mm is designed for comfortable handheld shooting, which is critical for a lens with such a long focal length.

Depending on your photographic needs, one lens may prove more versatile than the other.
