In the end a few TF just arent going to matter either way. Look how many third party PS4 games were basically identical to the Xbone versions, despite the large power difference. Look how many first party Pro games look better than any games on the X. The difference is going to have to be absurd, like 5 TF to 15, for anything to matter.
The one thing that could be a decisive difference, the SSD, has been confirmed the same.
