Wealth is calculated in many ways. Some more practicle than others. Hoarding gold is not very practicle. I won't try and convince anyone that there is not a market for the metal, this is useless and untrue.  For whatever reason society descided a very long  time ago that gold is king. So, be it. Gold, however, is not a 'storage' of wealth. It's an inflationary hedge against fiat currencies. Even prior to pegged fiat markets set the value of the metal via various mechanisms, some of which are still practiced today. The argument that governments hold the metal as a storage of wealth is simply untrue. The metal is heald by governments for the same reason I cited previously. Fiat is not pegged to gold anymore. It's all debt based.

To answer your question, I'd rather own a bar of gold. It's market value is nearly 1000$ (US). 1 US dollar is tradable at ~1.51 Euro or 104 Yen or 1/3 of a gallon of gas.

Note the specific statement, " Gold has few practicle purposes", implies that I already know the uses for the metal (gold), some of which you mentioned.

Uranium realy only has one use: power. Be that power be used as a weapon or to energize our gadgets, it's still power. 

Which is better depends entirely upon perspective.
