I was trying to identify neutral sites of several individuals' genome from a population, do you guys have any idea of what tools should be the most suitable ones?

The data is NGS, whole genome.

I'm not sure which tool is the most powerful as each one performs better using its optimal criterion. I think it all depends on the particular dataset that you're working with. As pointed out by Zev.Kronenberg, several methods can be used. Check MEGA and DnaSP tools, I think they have built-in functionality for such type of analysis included. If you want to determine gene-wide selection (or neutral evolution), you could try using Ka_Ks_Calculator by Professor Ziheng Yang.

A new (very user friendly) implementation of most extended haplotype test statistics is out.

From the manual:

selscan currently implements EHH, iHS, and XP-EHH, and requires phased data.
It should be run separately for each chromosome and population (or population
pair for XP-EHH). selscan is 'dumb' with respect ancestral/derived coding and
simply expects haplotype data to be coded 0/1. Unstandardized iHS scores are
thus reported as ln(iHH1/iHH0) based on the coding you have provided.

Here's the link: https://github.com/szpiech/selscan

Tajima's D, iHS, EHH, Theta or PI. Those are just a few, but it is hard to tell what you are trying to do.
