This one, Top 40 Chess, covers the top 40 players, with separate lists for classical, rapid and blitz ratings. It doesn't have all the features of the 2700 Chess site, but the reverse is true as well. Here are three pluses of the Top 40 site:
- The slider bar at the top of the page allows one to compare one day's list with another throughout the month.
- Clicking on a player's name gives the details of their rating change: who they played and both the game and the rating result.
- Having three lists means you know who the top 40 are in rapid and blitz. While one can sort the players on the 2700 site by their rapid & blitz ratings, it doesn't show players on those lists whose classical ratings aren't over 2700.
As noted above, the older site also has its advantages, so depending on your interests at a given time you might want to check one or both sites.
