Ballypinball is right with the colors. There is no way to make fluoroscent colors with an inkprinter. Therefor the BBB decals will not nearly look like the original in UV Light. Same for other colors.
I prefer licenced becaus they are mostly much better quality than inkprint. The glossy is also not my thing on my machines except if there are no licenced. But robotron is right .. there is also a lot of bad stuff with licence on the road. Licenced means not automatically better quality. Everyone has to decise what to buy for his budget. In eastern europe there are also shops cheaper than the guy from GB for inkprinted decals.
What I dislike .. try to get silkscreened IJ decals. There is only a resource in Australia and a set is around 500 dollar or so. Why ? Is there no way to make a new run of licenced good decals ?
For BBB I bought 10 year old NOS decals for hell lot of money ... but the glow in blacklight. Maybe for a VPIN project the repros are also fine.

Why I have my problems with retrorefurbs: A german guy I know made BoP 2.0 decals from the scratch. He did not steal the original design, he gave the files for free to others who asked for it. Non profit ... but now you can also buy them in GB.

However .. everyone has to decide for himself and his wallet WHAT to purchase. I prefer buying , if avaiable, second Gen. screen print. I have no problem with paying some more. Other hand, not all titles are available and some titles became rising prices ... due to not in stock regularly ... why do they not just print an other 100 pieces ..

eabundy: Sure ... the repros have thicker foil, easier to bring on and need not such good preparing work on the cabinet. The "art" is to prepare cabinet and backbox that you can bring on perfectly the thin licenced silkscreened decals. If you like the shiny look .. go with the repros ...

my 5 cent ..
