You have a pre-installed tool and a tool that looks better but which you need to install. When you need it for a rare task, and you administer many machines, it is easier to use what you already have on each of them.
Sorry, I don’t understand what you are talking about. Yes, you can run them in SSH session. No, you still need to have them installed on the remote machine to do this. And installing diagnostic tools is not only time consuming, sometimes it can be even impossible if you already get in troubles (and if you did not, why would you need them?).

Do these programs not work over SSH?

Hmm, that’s a fair argument. I’m pretty sure new server installations can just have their default program list modified though.
