Please help with tire decision

It looks as though rona has struck again.
I still have quite a bit of life left in my LT255/85R16 KM3's, but probably not enough to get me through the rest of the year.
Apparently all of the tires are currently sitting off the coast of Kalifornistan, and who knows when they will be allowed into the country.
On that note, the local tire shops only have the following tires in stock, none of which I have ever used.

Cooper ST Maxx
Falken Wildpeak M/T
Toyo Open Country M/T
Yokohama Geolandar M/T

Does anyone have any real world experience with these tires?
I use them for a mix of highway, dirt/gravel roads, back country exploring, old mine trails and occasionally some rough rocky terrain.

 

For your use I’d pick the ST maxx, the MT look awesome but the tread will be overkill. How did you like the km3s?

I have had three sets of KM3's and I have loved them all. But now they are on a nationwide back order with no foreseeable restock. My current set are four years old and have at least 1/3 of the original tread life. But this last winter showed me that they had passed their prime for snow travel.

 

Yeah I like the KM3 as well, great tire.

ST Maxx are great in the desert. Pretty good on road manners too. Spendy though. And heavy.
I've ran them since they were called Cooper STC. Guy at the tire shop told me it stood for Super Tough Compound, lol. I am running STT Pro's right now cuz I got a screaming deal, but will probably go back to the Maxx when they're done.

 

Yokohama Geolandar M/T's it is.
Called back and they said the only two they could get was these and the Toyo's. I was really leaning towards the Coopers, but currently unavailable through Discount.
Thank you all for your input. At least I only have to buy four of them, I can use my KM3's for spares.
