Well for me it's because I'm already more comfortable with computers and EFI than I am with carburetors. I'm 19 so I grew up into an injected world, it was never something new that came along. And while I can see the advantages of carbs I'm just more inclined towards EFI.
From what I read too, EFI is really the only way to do turbo setups to their full potential. But I've never actually done a turbo setup (on my first) so.....
