Divine Power is critical to Paladins, in particular- the PHB version doesn't have enough options for a CHA or STR primary Paladin to take at every level (basically, you have to have them as co-primaries). It also introduces Divine Sanction, which allows Paladins to function as zone defenders. The other * Power books have helpful options, sometimes even character defining options, but Paladins are really incomplete without DP.
