i have never done a side by side because it depends on how much time i have. but i think the the paper bag method lets you put the bud it a little wetter so you can get a bit stronger scent. you just have to keep on it or you'll have moldy or over fermented buds. but i have also got great flavor by skipping the paper bag. i use the paper bag method when i have more time. it draws out the drying process
