New details
So, their have been revelations and proofs.
So, while the Maytag and Whirlpool machines appear to have the same internals, they do have different UI layouts.
So let's start with some overviews.
These two searches list the new models currently findable on the web for both Maytag and Whirpool on applianceconnection.com.
As far as I have the overview each model has its manual listed on the product site.
Maytag:

Whirlpool:

First on the UIs:
Whirlpool uses the What to wash / How to wash logic from the TLs. They do have a presoak option that apparently dosen't drain after the soak. The "Steam" option appears to have the function of a heater engagement during the wash.
Maytag offers the same "Steam" option, but uses the usual cycle dial.
Pressing the cycle dial will run the "Extra Power" option. Opposed to the Whirlpool, that is a cold prewash that uses the bleach compartment in the drawer as a prewash compartment then.
However both offer a "Colors" cycle which seems like the "Normal" cycle without usage limitation.
Now onto the models that a shared and sold under both brands. I was abled to find out that these models share a lot of part numbers, so they are for the most part the same machines under the hood with slight differences:
The 56xx are the lowest end models I was abled to find.
Both the Maytag and the Whirlpool offer a 4.5cuft capacity there.
While the Whirlpool offers a small 1l Load&Go container, the Maytag has the better warranty.
The Whirlpool lacks any post-wash tumble feature as well, while the Maytag features the FreshSpin option (12h tumbles without fan).
Both are "closet depth" with less than 32" depth.
I found the parts manual for the Whirlpool version:

I had a look at the Maytag equivalent but can't find the link anymore.
Anyway the both share the same pump unit and heater according to parts numbers and the water system drawing clearly shows recirculation on this verry basic model already.
The next model up is the 66xx series.
The Whirlpool now has a bigger Load&GoXL dispenser that holds up to 2 liters of detergent.
The Maytag has a slightly bigger drum now at 4.8cuft and a 16h FreshHold option (uses a fan). It also has 2 cycles more, one of them being the colors cycle.
While the Whirlpool is still less than 32", the maytag is now about an inch deeper.
That was also the last parts manual I was abled to find:
https://aem.whirlpool.com/wdl/en/as...uments/201811/repair-parts-list-w11323671.pdf
Still, heater and recirculation.
Thus I assumed all higher up models will have a heater and recirculation as well.
Next in line is the 86xx series.
Both models are 5.0cuft now with about 33" depth.
Here, Whirlpool adds the Overnight Wash&Dry. This is a fan assisted system that supposedly also uses heat in some way, but claims to take about 6h 15min to wash and dry an 8lbs load. It also claims Nest Smart Thermostat integration, but no WiFi connectivity. The energylabel also says it uses over 700kWh per year compared to its smaller brother and the troubleshooting guides for the drying function do not mention any water connection, so I suppose it is basicly a washer dryer that vents the moisture into the room I guess. Also, a drum light.
The Maytag adds its first automatic dosing system here, but that is integrated in the drawer and only holds less then half a liter. It adds full WiFi connectivity and a 24h FreshHold option. The energy label here lists only 140kWh per annum, so no real drying capability, only overnight wash and dry for 2-4 synthetic items, not a quarter drum like the Whirlpool. Also, again, more cycles.
And as I said, I suppose both have recirc and a heater.
Now onto the models Whirlpool has to offer additionaly.
They do offer 2 smaller "closet depth" machines as well, the WFW560CHW and WFW862CHC.
The last number was exchanged for "C" as in "Closet"
Both have 4.3cuft capacity but still are 32" deep.
The lower end one does not have an heater apparently as it lacks a true Sanitize cycle (only Sanitize with Oxi) and the steam option. No further options either, but still the same cycle setup otherwise.
The higher end one is the same as the WP WFW8620 except for the Nest integration thing and that it "only" uses 430kWh per year due to the smaller load size for wash and dry.
And, as the TOL crown, Whirlpool offers a WFW9620 model, a fully fledged 33.25" deep complete washer dryer combo, with 5cuft drum, AutoDry, water cooled condensing system, seperatly selectable drying functions as a result, 2 Load&Go tanks (one large one for detergent and one small one for either detergent or softner), a touch screen and full WiFi connectivity.
It is still 120V and has a companion dryer, both avaible in gas and electric.
Drying times appear to be beyond the 4h range for a good load, the label cycle uses a 6h timed drying function.
Idea appears to be to basicly use it as a washer only during the day and for the night to use the wash and dry funtions.
