Ironically, if I remember correctly (far too lazy to google it right now), Arlington National Cemetary is built on his land, seized after the war. If so, it is both awesome and tragic.
Lee was a great leader, but I think his subordinates deserve a shout out.
Longstreet was unfairly maligned after the war for criticizing Lee, but his criticism was deserved. Longstreet was also a forward-thinking genius of defensive warfare.
Lee has gotten a lot of credit for Jackson's early war action, also. If Jackson hadn't been capped by his own boys, the war would have had a much different tune.
I'm not trying to discredit Lee, just trying to point out that he had some great help.
