White noise or nature sounds for sleep?
Both work by masking sudden noise: white noise is flat and uniform, nature sounds are more varied, and the better one is simply the one you stop noticing.

White noise is an artificial signal with the same energy at every frequency, a flat hiss. It covers other sounds very well and loops easily. Its downside is that some people find the hiss harsh or tiring after hours.
A river, steady rain or crickets are also broadband and steady, but they have small natural changes: ripples, drops, single chirps. Many people find that easier to ignore. A few notice the changes more than a flat hiss, especially when the recording has thunder or bird calls.
How to choose: if sudden noise wakes you (traffic, neighbours), try a wide river or steady rain first, because they are closest to white noise. If every change bothers you, take the flattest option and avoid thunder. Test each for three nights and compare. Comparisons between them are limited, so ignore claims about one best sound. Whatever you pick, use a long recording rather than a short loop. Three of ours are below.
Quick questions
Is rain white noise?
Not literally, but it is broadband and steady, so it masks noise in a similar way.
Can I play it all night?
At a low volume, usually yes. Keep sound away from your ear, especially for children.
