I've heard alot of bad things about Panaracers. Nokians are good tires, but a bit overpriced. Also look at IRC's offerings and give a look at Intense's offerings. Plus if you have the money look at a set of Maxxis Mobsters in the 2.5 setting. But if you do go with a pair of Panaracers, be prepared to change tubes fairly often since they are prone to pinchflats.
