Im wondering if there is any real benefit or difference between using Calibre portable on a computer vs. installing it.

I myself used the portable back when I wanted to run two instances of Calibre on my computer at the same time - I don't remember why but it was back in Windows 7.

I am reading where people have just put Calibre portable on their desktop and are using that as their main library and their way of "backing it up" is just by copying over the settings folders.

There has to be a reason why this isn't a good idea, but I can't off the top of my head figure out why.
