The "upside down" plug dates back to the days when everything associated with electrical installations was metal. The round top part of the plug is ground and not conductive, the bottom two prongs are hot (think non-polarized). If a plug was not completely inserted into an outlet and something metal fell into that open space, there would be an electrical arc when it hit a hot prong. Think hospitals, which is why to this day you will still see electrical outlets installed in this manner.
I prefer the ground at the top. When plugging in a cord by feel(behind the couch) the round pin won't accidentally go in any other opening but the right one, and when it's in the right place it's easy to line up the two blades. When you can see what you're doing the ground pin is easier to point and plunge which is half way to aligning the blades. xoxoxoBruce xoxoxoBruce

Am I exhibiting signs of OCD because I was more upset with the upside-down plugs, with the hole for the third prong in the top position?

No, that's common. Plenty of people were bothered that the screw slot wasn't vertical.

Reminder: it's against US electrical code to paint outlets. Paint the covers, sure, but don't paint the actual outlets.
