I just used the pinballdecals.eu for my tz restore - https://pinside.com/pinball/forum/topic/twilight-zone-restoration-1
I'm very happy with them. The biggest difference between them and the classic arcades decals is the gloss level imo. The ones from pinballdecals.eu are super glossy, and the ones from classic arcades are more of a satin finish.
I at least know that for sure with the tz decals. I bought a set of the next gen decals, and had to sell them immediately because the gloss level wasn't quite what i was looking for.
