I received a NIB GZ Pro on a trade, and realized I'm not up to speed on the Pro/Premium differences. I studied the feature matrix, but am now perplexed to learn that this apparently doesn't enumerate all the differences?!
Notably, from scanning a couple of threads, there are software differences.
Super Train Loops timed mini-mode is added on the Premium. I find this a little strange as it's not really particularly related to the different mechs, although the moving building is incorporated, it's certainly not required. The pro could easily have something similar, but it's complete absence is a little distasteful to me. I know Stern has done some topper-tied modes, but is this rule-difference unrelated to physical features something new?
I was pleasantly surprised that even the Pro has the same RGB LED spec and dual-color general illumination. But now I'm reading allusions to enhanced or extra lighting on the Premium? Are there truly more elaborate light shows programmed on the Premium? I would be particularly disappointed in this one, especially as the feature matrix seems to infer the lighting is the same on all the models.
For me personally, the biggest considerations are diversity of play and the lighting effects. I like how the building can divert to feed left or right flipper on the premium, as this varies game play. The MechaGZ turn table also gives that area some varying shots since it's now not static like the pro. The bridge does too, but seems more trivial so that one doesn't add much value. One thing that came to mind though, Stern could have easily kept diversion through the building on the pro with a simple and cheap single-coil Radical-style criss-cross diverter. I'm really disappointed they didn't do that.
Are there other differences that aren't covered in the feature matrix? Can someone quantify the exact lighting differences? Is this substantial and throughout the game play?
I'm having trouble deciding whether or not to keep the pro. I think it will come down to if the lighting effects are actually significantly different. When I played Iron Maiden Pro after playing the Premium a bunch, the more primitive lighting made the play seem less exciting.
