If you want to be behind the Kings bench, this is the place to be. I think every seat is a great seat on the sidelines. No other NBA arena will put you closer to the floor than Arco Arena (refuse to call it Power Balance).
It's an older venue that's showing it's age but the seats offer plenty of comfort and there is adequate space for your legs and elbows. Sections 114 and 115 if you notice on the seating chart will be the mid-court seats and the ticket price for those seats will be a little higher.

I've been to more Kings games over the years than I could count. I live closer to the city so I hate the drive out to it's location, it's out in the country where there is nothing to do around the arena.
