If you are confused because all of them come with so many good qualities, then keep in mind the following tips which will help you make up your mind and speed up your purchase.

Water Resistance

Nothing can be worse than getting your sleeping bag wet because of rain or other water contacts. Look for a sleeping bag that has a water-repellent material so that you can stay dry all the time.
Length

If you are very tall, then you might want to check out a bag that can easily fit you. When making your purchase, keep in mind the length of the bag.
Sturdiness

You would want to buy a bag which would last a long time. Especially if you regularly go camping or on other outdoor activities. Therefore, when buying your favorite sleeping bag online, look for the one which is sturdy to make your investment worth it.
