Pundit says Liverpool ace far superior to Tottenham star.
The Liverpool and Tottenham midfielders competed for a position in Gareth Southgate's England squad this summer and continue to do so.
Speaking to SkySports' The Debate, Pearce said Henderson offers much more than Dier.
He said: "From a choice between Henderson or Dier, after the World Cup everyone knows who by far is the best one.
"Henderson offers leadership as well, as captain of Liverpool."
England played the pair of Dier and Henderson together at points during World Cup qualifying, but the performances were slated by fans who felt they combined to make England far too negative.
Henderson has not been a regular for Liverpool this season due to the form of James Milner and summer signing of Naby Keita.
Liverpool were careful not to rush him back into action after the World Cup, while Dier has not had the same luxury this season due to injuries in the Tottenham midfield.
Both players are competing for a spot once again when England take on World Cup conquerors Croatia.
