Pro:
Best flow in pinball. Fast & Fun. It’s only drawback is a pretty major scoring exploit that is easy to get (easier than playing HOTK IMO). It can be fixed in settings but that gimps houses Baratheon and Stark which are already weak houses.
Premium/LE:
The scoring exploit is much harder to trigger on the prem, I ‘think’ the houses may be slightly more balanced on the prem. The light show and is great and whether you go prem or LE, the art blows the pro out of the water. It’s not the best for flow but still ok. The prems major drawback is the rules for the upper playfield, they don’t mesh too well with the rest of the ruleset but there is an extra multiball to go for that has little to nothing to do with the rest of the game but can be played out of sheer boredom.
All in all; both versions need some serious attention and polish in the code dept. if you want speed and flow, go pro. If you want technical and harder, go premium. Whichever you choose, the color dmd is an absolute MUST; there’s no point (other than scoring) for the dmd without the color.
