Breaking and joining a chain at a normal rivet can weaken a link. For some chains, you mustn't re-use rivets. Sheldon Brown has a good explaination of the why and wherefores.
I like those master-links, and cant think of a reason to avoid them.
your propably right but kmc ,s "missing link" is only a one off thing , once its on you cant break the chain there any more
i had to shorten the chain anyway so i keep their link thing in my punture kit for an emergency
