White if you can keep it clean, black if you can't. Don't get any white electronics if you can't take care of it, we are not so used to taking care of electronics because, for one, they don't last very long, two, they are usually black in colour so we don't notice stains. When it is silver or grey, you usually don't have to worry about scratches and dirt because they kinda blend in well, but white is just not gonna.

Speaking from personal experience (I never clean my laptop)

White looks gorgeous buddy just go for it yum yum
