The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon EF-M 32mm F1.4 STM and the Samyang 35mm F1.2 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. Samyang 35mm F1.2 is the longer of the two lenses at 74mm. The Canon EF-M 32mm F1.4 STM with a length of 57mm, is 17mm shorter. Besides being longer, the Samyang 35mm F1.2 also has a larger diameter of 68mm compared to the Canon EF-M 32mm F1.4 STM's 61mm diameter.

Below you can find a scaled side-by-side image of Canon EF-M 32mm F1.4 STM and Samyang 35mm F1.2 to get a better idea of how their sizes compare in real life.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Canon EF-M 32mm F1.4 STM weighs 235g, which means it is 185g (44%) lighter than the Samyang 35mm F1.2 which has a weight of 420g.
Filter Threads
The Canon EF-M 32mm F1.4 STM has a filter size of 43mm whereas the Samyang 35mm F1.2 has a 62mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 43mm filters that we recommend you to consider for the Canon EF-M 32mm F1.4 STM:
And these are the 62mm filters that we recommend for the Samyang 35mm F1.2:
Lens Mounts
Both the Canon EF-M 32mm F1.4 STM and the Samyang 35mm F1.2 has the same Canon EF-M lens mount. Some of the latest released cameras that are compatible with the Canon EF-M lenses are Canon M50 II, Canon M200 and Canon M6 MII.
Samyang 35mm F1.2 is also available in Fujifilm X , Micro Four Thirds and Sony E mounts.
Focal Range
Canon EF-M 32mm F1.4 STM is a prime lens with fixed focal lenght of 32mm which has an effective (full-frame 35mm equivalent) focal range of
51.2mm when used on a APS-C / DX format camera.
On the other hand, the Samyang 35mm F1.2 is a prime lens with fixed focal lenght of 35mm which has an effective (full-frame 35mm equivalent) focal range of 52.5mm when used on a APS-C / DX format camera.
