Love my pro. I prefer the standups to the drops. More ball action. The lack of the right diverter ramp is somewhat annoying on the pro - balls drop into the shooter lane and need to be auto-plunged back out with annoying frequency. But it's not "spend thousands of dollars" annoying. It's minor. You can mod disco ball back in if you really want it - I couldn't care less. Art on the pro is overall a better package, IMHO, but that's a matter of aesthetic taste. I like the premium cabinet art better, but it doesn't match the color scheme of the playfield. The art on the LE is too much. Too much red, too much yellow. No thanks. So pro wins, overall.
The other goodies I don't care about (figures, glowing speaker rings, powder coat, shaker, mixtapes and vinyl, etc...).
Your mileage may vary, of course. Stern appears to be selling plenty of Premiums and LEs, so lots of folks disagreeing with me, I'm sure.
