I thought about it... and actually had my SL2 listed for sale. 
 

In the end I decided 47 mp and 1/40000 SS was more important to me than better HIGH ISO. I don’t shoot video. 
 

I may wind up with the SL2-S at some point... but I will wait and see.

I dont care about video either.

Any thoughts on how many real world stops better iso SL2-S has?

Currently as least for my needs the SL2 does not have the best high iso performance.

 

hmmm......

Or you can:

1. Add an SL2-S... and keep SL2.

2. Buy an S1 for under $1500 :). Insanely good HIGH ISO, sane mount, and way cheaper. I have an S1 that I use for adapted Nikon glass and HIGH ISO when I need it.

In Jono Slack's review he believed it to be about a 2 stop advantage in favour of the SL2-S, however when he compared SL2 files that had been downsampled to 24MP he likened it to about a 1 stop advantage in favour of the SL2.

On paper it is one stop better. The tests are not yet there, but they will probably come in the next few days/weeks.

Jono made some comparisons. They showed that for me (usually using up to 800, in rare cases 3200) the SL2 is the better choice.

On the red dot forum you can see some photos, one taken at iso64000. It is impressive, that this setting still gives a usable photo. (But the noise shows.)

If we wait 3-6 years I assume all cameras will gain 1 to 2 stops. Just following the general trend.

Actually, there was no advantage visible once you compare same exposures (shutter speed and aperture).

1 stop iso better in real life is not that much better. 
 

 

That is typically the difference between APS-C and FF sensors, or between ISO 800 and ISO 1600. It could be a difference that matters.

High ISO noise performance will keep improving. I’m convinced of this.

https://blog.kasson.com/a7iii/sony-a7iii-raw-filtering/

But I did notice the spectacular noise performance on Bill Claff’s Photons to Photos site, especially the read noise at ISO 640, and that got my curiosity bump itching...The a7III appears, like many alpha cameras, to use the Aptina DR-Pix conversion gain algorithm, and to switch to high conversion gain at ISO 640.

...

If Sony is using these kinds of tricks to achieve their impressive noise numbers for the a7III, that would, I think, be a shame. This kind of thing is much better done in postproduction.

I usually live on or close to base ISO most of the time so ISO 100K means little to me. Since I print to A1 I also use those extra pixels. 

Also for me, noise is almost never an issue even at ISO 3200. A good image will survive some noise. It won't even be noticed or it can be used to deliberate effect. I think complaining about noise is just for people on forums and bloggers who test cameras for an hour or so. Colour science followed by DR are what I look for and even these fall way behind the lenses, handling, balance and usability of a camera.

Plus I like my tripods.....

 Kristian  Dowling, who is a prominent working photographer here in Australia, indicated at a recent webinar that the high ISO performance was about a stop better. He was a tester for Leica Australia. He commonly shoots starting from 1600ISO to much higher. Kristian is an extremely experienced pro and has had five years with his SL.
