In each corner of the 100 level at Oracle Arena, you'll find one large section (e.g.: 110) and two small sections (e.g.: 111, 112). Each of these sections offers a different perspective and experience for a Warriors game.
Using the seats in the southwest corner as an example, section 110 is an enormous section with 26 rows of seating. The first row is roughly eight rows from the court as it is located behind VIP and Floor seating. Despite being slightly behind the basket, these large sections offer good sightlines to both ends of the court. While you may be tempted to sit closer to the court, higher rows will have some of the better views and they're closer to the concourse tunnel.
The corner section closest to 110 is 111. This and similar (104, 118, 125) sections may be the best value in the lower level. The sightlines (angles to the court) from these seats are fantastic - giving you comfortable views of both ends. You'll also find that every seat is within 7 rows of the section tunnel for quick access to the concourse. Better yet, no row contains more than 10 seats so you're always close to an aisle. One drawback of these sections is that they don't reach down to the court. The first row, row 10, is about 18 rows from the floor.
Lastly, the corner sections closest to mid-court - like 112 - are probably the most over-rated. Located slightly behind the basket, these seats face forward instead of being angled to the court. This creates awkward and uncomfortable viewing angles. Sitting in a higher row will help you cut down on the angle. If that doesn't bother you too much, these might be a good fit. All rows but one contain 8 or fewer seats for some of the easiest in-and-outs and access to concessions and restrooms.
