If you intend to create more than four partitions, GPT boot suits you better, as it supports a maximum of 128 primary partitions in Windows, while MBR can only hold 4. Moreover, GPT performs better than MBR for hard disks larger than 2TB. GPT also offers higher data security and enhances the performance of your system if your motherboard supports UEFI boot. On the other hand, if your motherboard doesn't support UEFI boot, you have an older version of Windows, or your Windows is 32-bit, you should opt for MBR.
