I think you are right, however, i can't find anywhere a direct comparison. All reviewers can say is:
- if you have a M camera, the ef-m 32mm is a very good choice
- if you have a Sony aps-c camera, the sigma 30mm is a very good choice
This isn't helpful at all for those who choose a system not only for the camera, but also for the lenses, which in my opinion is a better approach choosing a system.
The person I was responding to indicated that he was not yet locked into a system. If someone owns a Sony system, it makes more sense to buy their 30mm f/1.4 than to change platforms and buy into the EOS M system just to access the 32mm f/1.4 (though some are now doing this). I believe the reviews of the Sony 30mm show that it has several weaknesses in optical performance that are better resolved with the Canon 32mm f/1.4 lens.

The Sony 30mm f/1.4 is well liked by the Sony crowd. I'm confident that I'd have bought it if I was using the Sony system. Reasons for me to ignore Sony in the past included issues with the Metabones adapter and a weak native lens selection (you either get poor quality optical performance or you have to pay more for the licensed lenses). Since I shoot a little Astrophotography, Sony is at the bottom of my list due to ongoing problems with star-eating algorithms on several models of Sony mirrorless... an issue that was never rectified with successive releases of newer "improved" bodies, despite the threat of Class Action suits and large petitions by Sony users who were angry that they were being ignored. That's just a few of the reasons why I chose to pass on Sony. I prefer Sony electronics for my home, just not for photography. A Sony user might find the EOS M lens selection to be a bit limited and the AF to be slower than what they're used to. This is slowly leveling out though with the latest models of EOS Ms and their new DPAF sensors. This is also why many Sony users are jumping ship to buy EOS M cameras and their EF-M lenses. Another member here noted that Sony users were leaving just to be able to use the EF-M 32mm f/1.4 lens now that they've had a chance to see samples on various review sites.

If someone is out to buy a small mirrorless APS-C system that is compact, I'd recommend the EOS M system for it's key Prime lenses alone. They cover most general uses plus a few specialist lenses for Macro and Ultra-Wide etc. The body of the camera (even though the performance with AF and image quality is derivative of the processor and feature-set) is less important than the lens. The lens is always the weakest link. Without good quality glass, the images suffer.
