I think I'm going to go with the partsexpress vinyl.
I ran my fingernail at varying strengths on both vinyls, and the smooth stuff definitely showed marks at any level. Running my nails on the partsexpress vinyl didn't leave any marks whatsoever, as it seems the texture really holds up. I personally won't purposely be scratching the vinyl, but as far as accidents are concerned, you never know what could happen.
The Aesthetic on Rich's vinyl is much better and more suited for the arcade look, obviously... The partespress stuff has a sort of electronic appliance look to it, as it was meant for... but if at the end of the day one is stronger and the other isn't, I don't know if I have much of a choice...
UPDATE:
Scratched both vinyls with a key and a screw...
In both situations, they left marks and gashes, but the textured stuff held up under a little bit more duress before giving in. Also, blemishes in the textured don't stand out as much as blemishes in the smooth..
