Looking at your pins and wants, I would definitely play the pins first. You have an AFM and IM, which are the faster type of pin layouts. TSPP is a fun/great game, but way different. I think WOZ will play similar to TSPP. Just by guessing and the layout, it really looks like WOZ will be stop and go.
Many collectors like variety of styles, others like to stick to a certain type of machine.
I would really play a pin first before buying. I have played a lot of pins that I hoped I would like only to feel disappointed. The reverse is also true.
