CPL at back light condition can be really poor for portrait. You lose about 1~1.5 stop light in shadow that difficult to recover, especially for subtle skin tonality. depend on situation, It will also add extra flare and reduce contrast.
If the light condition make skin exposure in the middle or up range of luminosity area, it will make skin color deeper to cut the flare out. I find CPL mostly does negative than help for my preference.
Back to topic, I like what I see in this GM, it seems Sony has found a formula of rendering for their lenses, it looks quite similar to 24GM to me. I am not saying this is the best approach or I prefer this to anything out there, but it seems works mostly especially for wide angle lens which are usually having problem on background rendering.
As for compare to Sigma, I think as long as Sigma offer f1.2, this will be unfair comparison as always, half stop doesn't sounds a lot, but when you compare f1.4 and f1.8 design, you will notice how much more challenge this half stop bring. If you still pixel PP its sharpness at f1.4 and compare to Sigma or any other lenses, I think you miss the point. I don't care record breaking resolution, it means nothing to me in real world use. However, This one do offer pretty good rendering to my eyes, even corner looks pretty good to me.
That one eye in focus is really sharp though! lol. Of course it depends on how you frame the subject...particularly for a fast wide angle...frame loose to pull more of the background in and there is enough DOF to keep most the subject critically in focus even at f1.4.
That said, I'm not really losing sleep over f1.4 vs f2 as I don't personally find the difference to be too material unless the light gets low and we're talking ISO values. All in all bokeh and rendering RX1 sonnnar has a very pleasing look despite being "only" f2. I suspect both the Sigma and GM will be competently sharp enough....it all comes down to rendering for me . If the rendering of the Sigma f2 is pleasing, I'll pass on the GM, and save some room in my budget and my bag.
I was mainly talking about sigma f1.2 compare to f1.4 GM. People seem suddenly forget how special that f1.2 is/was 
I don't really know how to compare New sigma contemporary f2 to this GM. I think GM will at least win on corner rendering of better performing on cat eye and vignette. Usually, it is not just vignette itself bother me, but alway a few rendering problems associated with such mechanical vignette, It is like stop down lens partial of the frame. Still, this sigma is very good at f2. At f2.8, it seems totally fine with corner. Size and weight is a significant merit for sigma. the performance and size ratio is a winning formula for me in this case and it doesn't change with this GM.
For 35mm, I think I would prefer neutral rendering than blur than harsh rendering. Neutral means not just blur quantity but keep background shape and rendering with smooth fade away, the next stage is smooth with lots of blur, this is mostly fine but just a little boring, and many time, stopdown a little may lead to better looking images, the worst one is harsh. This is not a hard definition but all 35mm lenses lie somewhere between. In this regard, lens speed of 35mm is really not a first priority for my use. (MY USE) That is why I still think none touch RX1 in my eyes. It is not just smoothness but everything as a package.
This GM is good. A surprise in term of size, I like what I see here, I assume it will offer another advantage over others: AF. That may be an important factor for pro who cover events. AF could be a big consideration in lens design in modern age. I just want to applaud good engineering here for a whole package offered: price, size, AF and optics. A pretty significant statement IMO.

Bravo. Very astute "The whole package"
But there is one Mirrorless FF 35mm, "The One" Just look at those MTFs

Curious to see how Both compare Sony GM 35 vs Leica SL 35. Already size is evident and then there is that DxOMark measurement comparing one of my personal favorite for Sony FE, the Sony Zeiss FE 35 F1.4 vs The One Leica SL 35/2 APO:
