Athleticism and activity
The English Mastiff is heavier but far more sedentary — a true gentle giant that relies on size and presence rather than active engagement. The Boerboel is more athletic and agile for its size and has a more active guarding drive.
The Boerboel also tends to live longer, with English Mastiffs often reaching only 6–10 years.
The verdict
Choose a Boerboel for an athletic, active guardian. Choose an English Mastiff for a calmer, lower-energy gentle giant — accepting its shorter lifespan and greater bulk.
