The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 16-300mm f3.5-6.7 C and the Canon RF-S 55-210mm F5.0-7.1 IS STM for their suitability to various photography scenarios:
Size and Weight Comparison The size of a lens is a crucial factor to consider when comparing two lenses. Sigma 16-300mm f3.5-6.7 C is the longer of the two lenses at 121mm. The Canon RF-S 55-210mm F5.0-7.1 IS STM with a length of 94mm, is 27mm shorter. Besides being longer, the Sigma 16-300mm f3.5-6.7 C also has a larger diameter of 74mm compared to the Canon RF-S 55-210mm F5.0-7.1 IS STM's 69mm diameter.
Below you can find a scaled side-by-side image of Sigma 16-300mm f3.5-6.7 C and Canon RF-S 55-210mm F5.0-7.1 IS STM to get a better idea of how their sizes compare in real life.

Canon RF-S 55-210mm F5.0-7.1 IS STM weighs 270g, 56% (355g) lighter than the Sigma 16-300mm f3.5-6.7 C's weight of 625g.
Filter Threads
The Sigma 16-300mm f3.5-6.7 C has a filter size of 67mm whereas the Canon RF-S 55-210mm F5.0-7.1 IS STM has a 55mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 67mm filters that we recommend you to consider for the Sigma 16-300mm f3.5-6.7 C:
And these are the 55mm filters that we recommend for the Canon RF-S 55-210mm F5.0-7.1 IS STM:
Lens Mounts
Both the Sigma 16-300mm f3.5-6.7 C and the Canon RF-S 55-210mm F5.0-7.1 IS STM has the same Canon RF lens mount . Some of the latest released cameras that are compatible with the Canon RF lenses are Canon R50 V , Canon R100 and Canon R50 .
Sony E , Leica L and Fujifilm X mounts.
Focal Range
Sigma 16-300mm f3.5-6.7 C has a focal range of 16-300mm and
18.8X zoom ratio which has an effective (full-frame 35mm equivalent) focal range of
25.6-480mm when used on a APS-C / DX format camera.
On the other hand, the Canon RF-S 55-210mm F5.0-7.1 IS STM has a focal range of 55-210mm and 3.8X zoom ratio which has an effective (full-frame 35mm equivalent) focal range of 88-336mm when used on a APS-C / DX format camera.
