Haven't tried either, doing homework on them. Seems the 35 is good for compact and using as bedding indoors. The 20 is for camping. Hope that's right/helps

Worst. Northface Purchase. Ever.
Bought this to replace my summer bag. I'm a very hot sleeper( i like it cold) go winter camping all the time. But I'm not using this for winter. It has a comfort rating of 39, a limit of 29, and a extreme limit of 1F. Took it on a month long hiking trip and when the nights started hitting around 45-40 I got cold WITH a Thermolite liner. The nights that were around 35 I had to use my liner, full wool layer, and fleece layer on my legs to stay warm. In addition to that the draw string cinch button is so small and useless you basically just have to pull and force it. It also has the other hallmarks of a crappy bag such as an annoying zipper and did not stop leaking down the entire trip. Very regrettable purchase. My last few north face buys have been bad. The products didn't last long but at least they performed. This doesn't perform and won't last long due to the leaking.

Would Not Buy Again
I am an avid car camper and bought this for my summer adventures in the back of my car. Although athletically it looks nice, it is not warm for summer nights. I found myself very cold at night after my first time using it and had to pack spare blankets for extra warmth. Also, I don't like how it does not zip down so your feet are trapped at the bottom.
