 Which AI platform is the most accurate?

I wondered if AI would be honest enough to tell me which AI platform was the most accurate, and I was pleasantly surprised that the 4 different ones I asked didn't outright say theirs. They each gave a breakdown according to different categories of which ones excelled at what type of search. 

Did all the AI platforms agree? NO. 

Here's the short breakdown for each:
