You like to move games. So I would start with TSPP and then get JP down the road when code is hopefully even better than it is now and prices may have dropped. TSPP code is obvs done and prices are stable. Who knows what the future is for JP but it seems unlikely to go up bc there are plenty available.
I know this is not the optimal way to look at your decision, but again in your case, I think it’s at least a little relevant.
