Spectravideo vs. Spectravision

[Room 34]

The AA rarity guide only lists Spectravision, but I have two copies of Planet Patrol, one where the label (and the imprint on the cartridge casing) says Spectravideo and one that is Spectravision.

 

I am wondering if one is more rare than the other.

 

Same goes for U.S. Games vs. Vidtec.

 

Thanks.
