To each his own.If you need one good combat skill, you can't go wrong with Long Blade.
!? Spear is easily the best melee class for two reasons: tied to max hp increase on level up (spear is the only weapon class governed by endurance) so you have heavy incentive to focus on spear from the get-go (big oversight on bethesda's part), and spears have the longest reach which is useful in many ways.
Though I agree that the reach granted by the Spear provides a considerable tactical advantage.
Also you only need one Spear - Spear of Bitter Mercy (though you have to do Sheogorath's quest to get it).
