I like my setup – Hans Dampf up front with Nobby Nick in the rear! In theory the HD’s give you better bite up front where you want it, plus extra volume for hitting big bumps, and the NN’s in the rear are better for rolling and therefore easier to pedal. I run 30psi in both and find the setup great for the usual trail centre hacks and in the woods over roots, big boulders and pebbly trails and in mud. A great all round Jack of all trades set up. Though I haven’t had a great amount of experience with other setups to compare, but i’ve not found it lacking so far. The only downside is its very pricey.
