Don't know if this is the right place to ask. I was just wondering if there is any reason to install PuTTY on a Mac?

I've been doing a lot of research as to why people are installing it on their macs and in tutorials they never specify why they are showing how to install it on Mac. Mac OS comes with SSH and you are able to save connections and everything so I am just wondering what you guys might know that I am not seeing.
