I think we can all discuss all the fundamental reasons of security and decentralization etc etc but the proof is in the history of Bitcoin.
Right, history is really invincible. Only one thing is saddening that we lost "Satoshi"; we got him by our side in Bitcoin misfortune and helped in developing but today we do not find him in the golden days of Bitcoin. Without this thing, the whole history is really invincible.Never been successfully hacked,,, Never refused or given back,,, And if I wanted today to spend or sell my BTC I could do that much easier than any other altcoin.
Even no one has ever been able to crack Bitcoin's private key partially. Although some developers claim to extract private keys using public keys, they have never been able to do that.some people are very shouting about 51% attack but I just hear this mystery all over the year, never seen practically.
This for me is reason enough for any newbie to choose BTC over anything else. Trust is something not rational correct? 
I don't know about newbie, but institute and government who has the power and has the ability to invest bulk money, their first preference is Bitcoin. Cause with the profit they also care about the security of their investment, and only Bitcoin is the real secured world.
