A quote one has provided to colleagues on this topic:
Although speed is the same between MBR and GPT disk partitioning, the latter supports volumes up to 18 exabytes with 128 partitions per disk while the former allows volumes up to 2 terabytes with 4 primary partitions per disk. On an MBR disk, the partitioning and boot data are stored contiguously. If this data is overwritten or corrupted, it’s difficult to recover. Conversely, GPT stores multiple copies of this data across the disk; thus, it’s easier to recover from corruptions on a GTP formatted device.
