X, For all intents and purposes, will be the strongest amongst all As, For he is the only A that finished the seed.
Not even Ayin. The Ayin we meet at the final part of the story is not even the true Ayin, he is still just a fragment like the ones before him, Like other As, He represents the ideal A, The A that Ayin wants to be, but ultimately cannot.
I will argue the Ayin now currently in the light is x. Because X is the only one who actually gone through everything, not the ayin we saw, That is just a final set piece that sent us on our way, ayin put The ideal A there as a final comfot before his death, AndX has all the memory pieces because Angela has already synchronized Ayins memory with X for thousands and thousands of times.
The original X in the game(Not the OCs)is nothing but another A by the time memory synchronization happened, because the beginning when you still need to be naive is done. The middle of the play needs you to have your memory so you can know what to do and what not to do, and the final part needs you to be strong.
