How good are Indian defenses nowadays?

The July 2017 issue of Chess lists the top twenty openings compiled from a list of 2094 May games where both players were rated over 2400 Elo. One can not take position on this list too seriously because it is greatly influenced by how the openings are grouped. For example, all the Retis are grouped together, while English is separated into 1...c5, 1...e5, etc. Nevertheless, for what it is worth, some of the list entries are: 116 Retis, 95 King's Indians, 92 Caro-Kanns, 76 Slavs, 70 Nimzo-Indians, 63 Najdorf Sicilians, 61 1...c5 Englishes, 61 declined Queen's Gambits, 52 1...e5 Englishes, 47 Catalans, 41 Classical Gruenfelds, 41 Queen's Indians, 37 Berlin Ruy Lopezes, and 36 Kan Sicilians.
