My favorite offroad tires for many years has been the D756. The 739 front I will pull of a new bike and throw them away

. The 756 has been replaced by the MX51, have not tried one. The D752 is pretty good for a budget knobby as well, have not tried one on the front.
For DOT tires the 606 is good. I just installed a Scorpion Rally on the front of the 630 and it sticks like velcro. Fantastic tire. If I can get it to quick wobbling at speeds over 65 and get some miles out of it I'll be a happy camper.
The trials tire on the front works fine on a trials bike but not for an offroad bite. Not enough bite for soft conditions, will wash out badly. Would be okay for slickrock. Most will run the most aggressive knobby they can find for the front.
The MT43 is also not so good for big bikes with high HP for riders that like to spin up. It will rip the knobs right off. And not so good for a DS that needs 60-70mph road running. But they are unsurpassed for trail riding and just never slip. In fact, power-slides or steering with the throttle is no longer possible. That tire just follows the front around corners, so your technique has to change a bit, takes some getting used to. They work amazingly well even in sand washes. Hooks up just as well as a knobby, way better in TST (tight single track). Two rim locks are recommended so you can run it at 6-8lbs offroad, 10 for fast dirt roads, and 20-22 for on road. The side walls are very soft so it feels like a flat tire on the road. Some guys are able to deal with that and run them on their dualsport.
