Depends when u go. I crossed Otay today (Fri eve) but ill use Ysidro Ready tomorrow night also thought week during early AM getting to work ill use Ysidro. Best to use Google Maps with a traffic layer.
San Ysidro Pedestrian West is the quickest way to cross border.
Otay table
I'd say Otay in my experience, especially if you're walking. I go there a couple times every two months.
