I have about the same amount of time on each of the pins and I think I would agree with DP. It is a fun pin. I don’t think Stern did a great job with theme integration on GOTR but it is a fast pin and was fun - I don’t think it would be a long term keeper for me but I could be wrong because I absolutely love my Ironman due to the fast/brutal gameplay. It is my favourite pin ever and one of the longest in my collection because it always gives me a rush and pisses me off. When I bought it I never thought it would last as long as it has (10 years now).
So which pin gives you that rush when you play? Good luck. Hey, if you guess wrong you can always sell it and replace it with another one and try again.
