Then again, Roger, despite all his artistry, finds it hard to overcome the Energizer bunnies in the top 4, and his matches go form the sublime to the unwatchable as a result.
So it depends on whether you value quantity or quality. For quantity i.e. time per match, these 2 are probably a good bet, slowly being replaced by Murray-Djokovic.
