Henman. The head-to-head and weeks in top 10 prove that.
I don't think H2H proves that much really...It doesn't represent the player's consistency, titles or ranking.
Greg. As he was the one to actually make a GS final. Also he won more titiles and gave a lot more support to Britian in the Davis Cup. Henmen abandoned us. The pri*k.
Apart from calling him a pri*k... you do have a good argument however Henman got quite deep into Wimbledon consistently every year
