The verdict, by the numbers

Fit beats ranking, though. Melatonin is the better match if your problem is timing problems — jet lag, shift work, a drifted schedule. GABA fits little — most can't cross into the brain. If you're unsure which problem you actually have, the 60-second Finder quiz sorts it.
