In the past, I was told that a quick format would be more likely to have errors than a full format. I've had the occasion to have a floppy disc that I quick formatted refuse to function, but after I did a full format, it worked fine.
Now that you've installed almost all your programs and utilities, its a bit late for asking, unless you want to do a full format and install everything all over again. Your main risk is that at some point, you'll try to install something and find a disc error. Then again, that may never happen.
For myself, I always do a full format now even though it takes a lot longer, because I don't like to get a bunch of stuff installed and then have to start over. But that reflects my experience and may not be true for yours.
