It's a tough one I know.
Just Relax and have Fun with it.
The wall is a complete boondoggle but other than being a complete waste of money I don't think as many people get hurt by it that do by a no-deal-brexit, so, my vote goes to the no-deal-brexit.
I'd say any Brexit deal is worst than the wall. The wall is just a symbol now, a great big phallic symbol for Trump, Brexit steals our kids future
Peace through peace.
