Now with AD Sion, you wont have as big of a shield, but your health pool will be higher thanks to maxing your E first. You'd want Atma at some point, so you got some armor and Banshee's Vail is your best bet for more HP/MP and especially Magic Resist. Plus you wont get shut down as easy if they decide to try to CC you right off the bat.
But regardless, AP Sion has great burst potential mid-late game where as AD Sion's damage output just rises as the game gets further as well as his HP pool. AD Sion is one of those *******s who can start snowballing stupidly easily and thanks to the hard stun he can get those kills he needs.
