I don't think I agree with you on this. The basic reasons behind why bitcoin is more valuable than other cryptocurrencies are;
1. Bitcoin introduced blockchain technology which led to the introduction of other cryptocurrencies.
2. Bitcoin is the father and king of all cryptocurrencies.
3. Bitcoin introduced financial freedom to everybody no matter your social status.
Might I add that not every specs in the specsheet are necessarily used by the vast majority of people going about looking their cryptocurrencies. For one, nobody really cares about the fancy mechanism and lavishing technical aspects of a cryptocurrency as long as they can be safe with it and their funds are not easily taken away from them. Also, it is not unknown for everyone that cryptocurrencies are being used mainly for trading and trading alone, nothing more (or I could be wrong here). Bitcoin fulfills the basic necessities of people choosing cryptocurrencies over fiat money, and its
simplicity never ceases to catch the interest of the masses.
And also the value it created in the course of a decade, too.
