Actually, other than costs, the two changes to rabadons and void staff are an extra 10% ap to rabadons and another 10 ap to void. If anything, the mr threshold is even higher now. It should be noted that Ahri has received both nerfs to both her base damage and ap ratios, with the nerfs to the ap ratios hitting rabadons effectiveness and both nerfs hitting void staff.

I think the video doesn't take into account other items. It just compares the two individually, so you may be right about the overall ap changes making void better. If I have the time (and patience), I'll go through the calulations myself to check.

Honestly though, if I had to pick one or the other, I'd go with void. At low mr, you'll be doing close to true damage, meaning you'll still be shredding through targets anyway. At high mr, rabadons becomes less effective. Void stays relavent in both situations.

Of course all of this is overall pointless, since you're probably going to get both items in most games anyway.
