Why Orochimaru's Edo tensei gives summons white eye but the recent edo tensei has the black eye? I'm just wondering why the first and the second has white eyes and their faces are clean no cracks?
When Orochimaru used that jutsu against 3rd Hokage, he hasn't mastered it yet, which is why both 1st Hokare and 2nd Hokage were that weak. With weak I mean they were not revived with all their power available for them to use.

Later, Kabuto mastered the jutsu, thus enabling him to summon the dead with all their power available for them to use. It seems that this also makes their appearance change quite a bit like you noted, in that they have different eye color and cracks.
