Worth experimenting with both, and your preferred choice could depend on the style of music you play and not just what model of guitar you have chosen. In my experience: 80/20 = Brighter, and a more pure fundamental tone from the root note. Don't last as long. Phosphor = A bit darker, and also more complex, like the overtones are slightly emphasized. Last longer.

I haven't compared these in person, but the pictures show that the 50's Original has a straight-line saddle that is angled for compensation. And the J-45 Standard has a more modern "staggered" saddle, in addition to being angled. I've always thought that the staggered saddles are better for intonation, so how much of a difference does it make in practical terms? Does the old style saddle of the 50's model mean it will always have slightly worse intonation?

I see lots of Vintage Mahogany action going on. Here's a pic of mine. It wouldn't really be my first choice aesthetically, but I bought it because the mahogany/Burstbucker V combo makes it the best sounding guitar I've ever played. The true definition of a "studio".
