I know AM is dying slowing..But if you can choose
I know IBOC is bad on AM..How about AM Stereo??

AM Stereo or IBOC

since 90% of AM stations appear to be programming some sort of talk format,
the expense of going stereo probably does not make sense for them (which makes
me really wonder why AM talk stations run IBOC)

Definitely AM Stereo.
There are some air checks from KCJJ which you can download and hear. Broadcast in AM stereo, but keep in mind the MP3 format removes a little of the quality. The music sounds pretty good in my opinion, but it sounds better on my own radio.

I wish I could have heard their quadraphonic radio broadcast last year, but I unfortunately missed it. Surround sound AM stereo. ;D

AM Stereo...now THAT was innovative....
Unfortunately, the "free market" approach to system adoption was most than just bizarre, it was ABSOLUTELY INSANE.
There were 5 different incompatible transmission systems if I recall (seems like nobody ever learned the lesson of Quadraphonic.) And there was a switch on the Sony AM Stereo radios they had when AM Stereo debuted that let you pick from every one of them.
Even more amazing, even the lowest fidelity, 1000% Monaural narrow bandwidth AM rock station like KJET was on 1590 kHz in Seattle sounded far better on those little Sony AM Stereo radios than how they sounded on your average AM radio at the time. Not quite FM, but significantly better than you'd ever expect......
In my experiment (and maybe it's my ears), I found the Kahn-Hazeltine setting somehow worked better for this station than any other. Even though KJET didn't broadcast in AM Stereo. At all.
But who wanted to do that for every station they tuned in? An uber radio-geek perhaps, but your average consumer wanted it simpler. You turned something on, it worked, no fussing around with little switches you could barely read - if you even KNEW what station was transmitting what system (very few AM Stereo stations ever revealed anything beyond "We're now in AM STEREO!" or some derivative in their promos for it back then.)
And that's what killed it. Electronics manufacturers, radio station engineers and listeners were like, "WTF?" Everybody simply gave up and hoped it would all get straightened out.
It didn't until 1993, but by that time any potential for AM Stereo was lost to the inevitable public apathy.
Maybe AM Stereo could have had a leg up and may have even become successful if the FCC picked a system and mandated all stereo radio receivers include it. But there's another reality.......
The entire concept (while definitely worthwhile) also came too late. If they had debuted AM Stereo in say, 1972 instead of '82 (with one system, I think Kahn was the one they were experimenting with, and mandated it to manufacturers), it would probably still be here. And AM music stations overall would have had a fighting chance through the '80s. But by the end of the '70s, people were already moving to FM.
It was a chance lost......
But as far as AM IBOC goes - FORGET IT!! "Sounds like FM!" my fanny! There are more digital artifacts in IBOC (AM as well as FM) audio than there are in the Smithsonian! And don't EVEN get me started on how AM IBOC sounds like on an analog AM radio!

AM stereo wins here too.
AM stereo is better, and I always had a soft spot for Kahn's system. Although I've been concerned about Leonard, himself lately.
