Let me summarize things here quickly. Out of both tires, the Kenda Klever does better with wet roads, fuel economy, tread life, and witner traction. Whereas, on BFG KO2, you get a superior mud and rocky terrain traction, basically a majority of off-road terrains, except for sand. And on-roads, it renders superior dry traction as well.
Mickey Thompson Baja Legend EXP is although not a great tire to have on-roads, it really shines on rugged terrains on nearly all sorts of surfaces (expect for rocks). BF Goodrich KO2 on the other hand, does better with dry and wet traction (though overall it's wet grip is nothing to praise for) Moreover, you also get superior winter performance, fuel economy and tread life with the tire as well.
Out of both the Falken Wildpeak AT3w provides you with a superior wet grip, and a comfortable ride on pavements, whereas on rugged terrains, it's nearly better in almost all of them, as ti features a more open design with a lot of tread depth. On the other side, the Pro Comp AT Sport is better on dry roads, provides better fuel economy and tread life and it's durability is almost on part with it's counterpart providing 3 ply sidewalls, so it's not too far off on tougher tracks off-road.
So out of both tires, off-road Wildpeak AT3w provides you better sand traction and grip on gravely roads, and on roads, you get an enhanced traction on both dry and wet pavements, slightly better tread life, better fuel efficiency, and overall comfort. On the other side, the Mickey Legend EXP gives you a good traction on highways, but only when things are dry, though off-road the tire is a beast, conquering rocky and muddy terrains like a pro. Though despite having all season compound it lacks on snowy terrains, and it makes sense why it's not rated with sever winter ratings like its competitor.
So we have learned here that the Goodyear Ultraterrain features a structure which is better on dry road (especially when it comes to steering response), fuel economy, winter traction (lighter terrains only), and off-road does a better job when it comes to gravely roads. Wildpeak AT3w on the other side, is great on wet roads, provides superior comfort, and a quieter ride, and is a great pick for rocks, sand and mud, as it offer bigger groove mouth.
Toyo Open Country AT3 provides you with better dry performance, and tread life on pavements, and on rugged tracks, it brings better traction on rocks. Kenda Klever AT2 on the other side, features a supple tread compound which yields superior wet and winter traction. And the tire's lighter weight also allows it to be great for sand climbing and fuel efficiency.
Let me close this up by explaining both on and off-road performance. So on roads, the Toyo AT3 does better on dry roads, provides you with better tread life, and is quieter off the two, whereas the Goodyear UltraTerrain provides better fuel economy, and wet + winter grip. Off-road besides sand traction, where Toyo AT3 has an upper hand, the Ultraterrain takes care of the rest in a better way.
Although out of both the Cooper ST Maxx lacks a little on highways, especially on wet ones, it really makes up for it with it's off-road performance. Though still if you want to find a better balanced on and off-road tire, you should go with Falken Wildpeak AT3w.
Overall both tires have similar dry and wet traction values on pavements with only minor differences (mentioned them all above), though Hankook Xtreme with next gen compound provides better all season traction that's why it does great on winter terrains. Moreover, you also see better results on this tire in terms of fuel economy and off-road, on sandy dunes. Toyo AT3 on the other hand, gives you a quieter on-road ride, more tread life, and off-road it rocks on rocks and is also good enough on muddy terrains.
Out of both tires, although their dry traction is on par, wet traction is seen better on Nitto Nomad Grappler, as the tire features superior siping, which also provide enhanced winter traction. And off-road, it provides superior sand traction. Toyo Open Country AT3 on the other side, is better with tread wear, and provides you with a quieter ride, and although it's mud and rocky terrain traction is not so great, its still better in comparison.
The Dueler AT Revo 3 is a great catch for daily driving, though you would have to compromise a little on wet roads. Wildpeak AT3w on the other side is great with wet grip and hydroplaning, it's going to consume more fuel. Though you also get enhanced off-road traction with it as well, as that durability comes from a thicker tread rubber and solid internal construction.
So overall, although Cooper ST Maxx provides you with a decent on-road grip on dry (especially directional), with such wider grooves it's still not enough compared to its counterpart. And that goes especially for wet traction, though its not good on both tires. Toyo AT3 on the other side, performs better in nearly all on-road metrics, and lacks off-road comparatively.
