You've got to be joking. Neymar impacts games at least as much as Henry, if not more.
If you want to swap stats, here's one where you can actually compare the 2 because they were in the same team, same league. Henry is 29/30, Neymar 22/23.
Henry at Barcelona playing second fiddle to Messi, 35 goals and 23 assists in 90 games.
Neymar playing second fiddle to Messi, 70 goals 35 assists in 100 games.
Neymar on form is the only player who gets close to breaking the Messi/Ronaldo top 2, and injuries and moving to France have stopped that conversation but he is a ludicrously good footballer and sorely underrated because people don't like him.
Neymar was better than Messi at some really big times for Barcelona, like the famous comeback against PSG which was all down to him, the Copa del Rey final in his last year there, the semi finals against Bayern when they won the treble.
