EFI or Legacy

Which option would be recommended to install the OS. Boot my flash drive from EFI or Legacy mode?

I would always go for EFI unless legacy is compulsory.

i trued to install Parrot 5 on my laptop (dual boot) several times always gave me an error (dont remember what they were their were 2 of them) had to boot in legacy. got it up and running finally lol just my 2 cents
