I have not played GNR yet, so take this with a truck of salt, but I think it depends on the playstyle you prefer. I am a huge fan of Stranger Things, but that is because it reminds me of a different theme, slightly different layout of AFM. If you like those classic B/W titles where you shoot the large toy/object in the middle of the playfield, then I think it would be a good choice. If you prefer the wide body pins, then stick with Wonka and GNR. I think either way you have good pins to have some fun with. I do think its important to have different style games though, and Stranger Things has a classic 90's feel to me, that no collection should be without. So, while I am sure I am in the minority here, I say ST.

Enjoy your new space and be prepared to have less furniture in the house to make room for more pins!

Are they? I thought they were all wide bodies
