important to restate, perhaps, is that all these things can help. However, it's wise to choose the mildest wherever possible, and try to use them ONLY when you know you are having a problem with sleep. I know so many people who simply fall into the (bad) habit of popping the dose of whatever every night, kinda subconscioussly thinking it's just another part of their supp regimen. Then, after a time, you've created a situation for yourself where your body EXPECTS the thing and eventually NEEDS it in order to rest/sleep. That is what we refer to as chemical dependency. Further, everything (even herbal stuff) after a time will probably have an eventual lingering effect, making you drowsy the next day, lethargic, possibly moody. Again, it's not that these things are bad, or don't have a place. It's just smart to use as necessarry.
