Doors question.

I noticed when looking through a lot of builds that everyone makes them flush. Is there a reason to make them flush vs having it overlap the sidewall? I have to build mine next so i'm curious on what everyone thinks?

If the door is proud, It seems it will always be tough to not channel water into the gap at the top and, while moving, the forward edge.
