The debate on which is the "best" chess website tends to be subjective and thus is inconclusive. On the other hand, the site that has the strongest players should be objectively ascertainable provided metrics are available.
So which is the strongest chess website in terms of:
- Number of registered titled players (FM, WFM, IM, WIM, GM, WGM)
- Number of active (routinely visit) titled players
- Number of super-GMs (> 2800)
- Or other verifiable metrics.
