From my experience, I think most Pros are as good and, at times, better than the LE.
Tron, for example. Alot of folks think the LE is better. Personally I prefer the Pro. The LE has drops for TRON and that means I cann't bank off the targets to hit GEM. That would kill the game for me. Hitting the GEM shot is hard and I use the stand ups all the time.
The mini playfield in AC/DC? No biggie and not missed at all.
Star Trek? The Premium/LE look amazing and if you have the cash go for it, but the Pro is just fine and doesn't seem to be missing much other than bling. I have the Pro with the alt transite plus Refinery Backbox and speaker -- lighting is tied to the game and it looks amazing. I got it HUO and saved over $2K vs a Premium. I cann't justify the extra cash just for looks.
The only exceptions for me are X-men and Avengers LE. In the case of X-men I really like the spinning disk and pop up Night Crawlers. At the end of the day, though, I'm not sure it's worth the headache of the moving Iceman ramp. For Avengers, I think the Hawkeye ramp improves the game play tremendously and the LE is the only one I would want. The price difference, in the case of Avengers is minor, and you get alot of bang for the extra buck.
