Funny, I disagree with this entirely. I'll take ACDC Pro over the Premium all day for playing. Just to point out there are different opinions.
I'd also argue X-men is worth the LE cost above the Pro.
Quoted from Whysnow:
really? I thought he always went Pro first and kept in mind the general idea for prem additions?
Borg has said he does Pro first and then adds, Trudeau has said he does LE first and then removes. I tend to like Borgs Pros above the Premium, although again it's just taste.
So anyway, since I'm apparently not biased by owning the Premium...
I played both extensively before I purchased. I adore the theme, but as the lack of Indiana Jones games in my gameroom shows, I won't buy a game for the theme if I don't like it. And I thought I might not get a Ghostbusters.
I spent a long time on the Pro and couldn't figure out if I liked it much or not. I spent a while playing a premium, figuring I wouldn't like it enough more to justify the cost difference. In general, I find the Pro versions of Stern games to play faster, which is a huge thing for me.
GB Premium is the faster game, and it sits my basement by virtue of it being awesome, more so than the Pro. Although I did get a Pro translite because that's so much better. So, a counterpoint to your points...
You said: Predictiably random slings which favor skill over luck
To me, this is like the Iron Man argument that people used to say which said that Iron Man had no skill because of the monger magnet, yet I will argue that if you hit the monger in the right spot, you can control the magnets.
With the exception of multi ball if you are shooting well, nothing hits the slings. So if you don't want them hit, shoot better. And yes, I know that's really tough, but it makes the ball times shorter, which I really like.
You said: Better left ramp shot and right lane feed
I don't find any problem with the left ramp shot on the Prem, but one thing that bothered me on the Pro is basically everything returns to the right flipper. The left flipper on GB doesn't have many shots as is, but at least by making the right ramp go the left flipper, you have a way, even if dangerous, to safely get the ball to the left flipper via a shot. On GB pro, no such shot exists, making the right / left flipper imbalance even larger.
I also found I couldnt hit the left ramp with a backhand on the Pro but can only the Prem, although I'm not sure that is playfield geometry or just bad flipper angles on the pro I was playing.
You said: better slimer shot
I disagree. Slimer's left to right movement causes blocked shots to some things beyond him to the point that I often find myself timing my shot to avoid him so I can hit the ramp or whatever. I think that's a strategic element.
You said: better right ramp (less rejects once adjusted) and better that it does not return to same flipper
For all the stuff said about right ramp rejects, my game has almost no issues with it out of box. The Prem I played before my decision also had no issues, although they spent a bunch of time adjusting theirs. I've already detailed why I like the ball returning to the left flipper more above. And, the right ramp shot on the Pro is slow. I like a fast game.
For the record, I really like the idea of both the pro and Prem ramps, and I hope what was used in the pro is done again somewhere when a more strategic element might be able to. Be used. I love the subway dip on the premium top.
as mike notes, better flipper feel and fewer airballs
What is different to cause less airballs?
In my experience, the Premium I played had way better flipper feel then the pro. However, it seems that the early game were shipped with the flippers too low, and this has now been corrected. More Pros were made after this so I will say it's more likely to play a correct flipper alignment Pro than Prem, although this should be an easy adjustment to make.
So, you can legitimately like the Prem better. To me, it is the faster game (my favorite part of any game is speed!) and more balanced left to right with shots. That is worth it to me.
As I mentioned, Pro has the best translite (by far). The Ecto Goggles thing is stupid, although non pinball players say nice things about it.
I personally really don't like the Slimer edition and if you offered me one straight up for the Prem I have, I would say no.
