I wouldn't recommend them for first-timers.

Mastiffs can be loving companions, but they are not ideal for first-time owners. They need proper training and socialization early on. Their protective nature can lead to issues if not managed correctly. If you're ready for the responsibility, they can be sweet and loyal dogs.

Mastiffs can be a handful for first-time owners. They are large and powerful dogs that require consistent training and socialization from a young age. They form strong bonds with their families and can be protective, which can sometimes be overwhelming for new owners. Their laid-back demeanor can be a plus, but their size means you need to be prepared for their physical needs. That being said, if you are committed to training and understanding their unique needs, they can make wonderful family pets.

Mastiffs are gentle giants, but they require firm training. Their size and strength can be intimidating.

If you're a first-time owner, I suggest doing plenty of research first. Mastiffs have specific needs and can be stubborn. They have a lazy side, which makes them less demanding for activity, but they still need regular exercise and training.
