While corner sections in the upper level at the Honda Center aren't exactly ideal for a basketball game, these seats are usually the preferred option over other budget seats like those behind the basket.
In almost all instances, you'll want to be in the lowest row possible. This will keep you close to the entry tunnel at row D and the views will be far superior to those in the highest rows.
For added convenience, look for tickets in narrow rows. For instance, rows A-C in sections 405, 407, 409, 414, 416, 418, 427, 429, 431, 436, 438 and 441 have six or less seats per row. This is helpful if you find yourself getting up and down from your seats a lot (if you're annoyed by people who do). Conversely, rows A-C in corner sections not previously listed all have 16 seats and are the largest rows in their respective sections.
