Ugh.... that list on The Imperial Library was based on a "if they made a TES fighting game who would be the strongest character", not a "who is the most powerful in lore".

But, besides that, Talos is the most powerful character because he has CHIM, making him equal to Vivec.

However, unlike Vivec, Talos is also comprised of the unison of three Shezarrines, Tiber Septim, Ysmir Wulfharth, and Zurin Arctus, making him the space god Lorkhan re-incarnate, so, he gets some more power from that.
