Lee was still fighting a Napoleonic war, while Grant understood he was fighting a Total War. Lee never understood the full value of logistics. Grant did: not only how to take maximum advantage of his own but how to deprive the enemy of his. Lee fought in search of an eventual victory. Grant fought in accordance to a plan laid down in advance to achieve victory. Lee at Gettysburg proved how rigid a tactician he was through his stubborn inability to change a plan when circumstances demanded it, while Grant had the capacity to adjust his plan to fit the prevailing conditions. Grant was the general who, as Sun-Tzu would phrase it, made "many calculations in his temple" prior to battle (campaign), while Lee in comparison made few or none. Lee succeeded against incompetent or timid officers, while Grant succeeded against some of the South's best generals in terms of both ability and boldness. Up until the arrival of Grant, Lee largely got away with dictating the tempo and pattern of the war in Virginia. After Grant arrives on the scene, Lee never again has the initiative. Lee the Napoleonic general was then up against Grant the Modern general, and he never stood a chance after that point.
