The 390s have a great noise floor when properly tuned up. Other
than that, a modern PLL receiver has many more features.
The question was about AM mode. There's no bells and whistles on an
R8B that make it better than an R-390A for AM radio.

David:
Don't get me wrong - I love that R-390. But you're wrong about the bells a
whsitles. A sync detector is a wonderful AM tool. A sideband selectable
sync detector is even better: reduced fading distortion AND less adjacent
channel interference.
