I understand that Vitalik can be seen, or heard, or talked to whereas none of that can be done for Satoshi, he hasn't been around for years now. All in all I would say that the most logical argument for Vitalik would be the fact that he can say his thoughts and we can know about it, unlike satoshi who we do not know even if he is alive or not. Plus, ethereum became big, and if it became this big then we have to accept the fact that Vitalik had something to do with it. You do not "manage" the progress of a currency and get it super high and ranked so high and stay so high for so long without ever getting some kudos from the community time to time.
