I find it’s easier to regulate heat from the bottom zipper most of the time. Also if you have any belted gear or just need to grab something in your pockets it’s easier than a full unzip. Or if you’re a guy and you’re taking a piss.
Or you can grab the corners, wrap them up over your elbows and pretend you can fly.

The bottom one is used to give more room when you sit down or need to get stuff from your pockets.
