Best brand for residential water heater (tank)

I see a lot written about performing a quality installation. What exactly is a quality installation? Thanks.

If a plumbing inspector will pass the water heater and put a sticker on it then that would be a quality
installation in my book. When you see a water heater with the relief valve hole plugged off because the
guy didn't know what to do with it then that is NOT a quality installation.
