The south structure is directly under the flight path, so not a lot of side angle; the north one, being larger and angling awayfrom the flight path, gives you a greater choice of side angle. Up to you. When I lived there many years ago, my favorite spot was always on the sidewalk on Laurel, positioned differently to catch landings or take-offs. I especially liked being near the intersection of Laurel and Pacific. The wall to deflect the jet blast wasn't quite so large then, and the wind and heat made it very visceral.
