You could argue that these have a similar result. If you're just reinstalling Windows then you don't need the additional write cycles of a secure erase.I have wiped a SSD instead performing a secure erase
Most generally any disk smaller then 2tb should be mbr.
If you boot the installation media via UEFI the OS will partition in GPT and install as 'UEFI mode'.However if you create the partition table with Windows it'll still create a legacy MBR partition table and insert the first 4 partitions.
Too bad some BIOS force you to use Secure Boot in UEFI mode and thus can't boot from a flash. Drives me nuts.If you boot the installation media via UEFI the OS will partition in GPT and install as 'UEFI mode'.
