Linux is not better. Linux looks better, feels better and so on but under the hood it is just a rehash of the predecessor of plan 9.
I'm using linux every day on both my desktop and a whole army of servers and I have some experience with both plan 9 and other (micro kernel based) systems. Linux (and in fact all Unix flavours) have some systemic problems that those other os variants attempt to address. That the user experience is less polished does not detract from that.
Maths don't enter into it.
To re-phrase your analogy: Linux is a crocodile, it is ancient, dangerous and well adapted to its environment. So well adapted that it is a force to be reckoned with, even if you're an advanced creature from the future.
