I have to agree with this. Whether flying UA or ANA, I almost always use the ANA lounge located in the 50 gates. It is quite nice!
There is an underground tunnel that you can walk between the 50 gates and the 40 gates, so I don't mind using the lounge that is not closest to my departure gate. It also gives me a chance to stretch my legs before a long flight.
