The new RG1550 has a maple board but the old RG550's had rosewood (well my mates 550ex did, i'm not sure about all models). The new RG2550 has a rosewood board but it is of course more expensive because it has "better" pickups in it.
I just got a new RG1570 and, apart from the intonation on the bottom E (which i'm trying but failing to set right), it's a fantasic guitar. I'd go for the RG if I were you, but then in a personal thing and the only way you'll deside which is better is to try them both out. Just remember that they'll both sound pretty much the same if you put Evo's in the RG coz both guitars would have the same pickups in a basswood body, so it's what you like the look and feel of which are the deciding factors.
I don't know the differance but the RG1570 has the edge pro and the JEM555 has an edge pro II. All the other new JEMs have the edge pro as well so i'm assuming the edge pro is better in some way.
