If you're looking for all-mountain type traction and durability, the Hans Dampf is a great choice. I would also recommend you consider a combination of Specialized's Purgatory in the rear and Butcher up front. Both tires are offered in several casings and widths, so you should be able to cherry pick your favorite combo for your needs. Specialized also beats other tire manufacturers hands-down in price right now, if that matters.
If you like Maxxis, more aggressive tires from them would be perhaps an Ardent, which rolls really fast and yet is still quite grippy, or one of the many, many variations of the Minion DHF which is offered in several different trail casings in addition to the traditional HD DH casings.
You didn't specify whether you are looking for 26 or 29, but I've based my recommendations on 26. 29 might vary a little as I am still experimenting with a number of tires and combos on my 29er. 27.5 or 650B is really limited at the moment in terms of options.
