I would broadly expect software made by most camera brands to be shit, while I would expect a developer who creates their own hardware projects (generally, not talking specifically about cameras) to range from idiots who have no idea what they're doing (like me, though to be fair I also wouldn't release it believing it to be good) to highly skilled coders who would get it right despite being on their own.
So I wouldn't automatically assume that a product like this would be better designed, but I would think there's a chance it might have been!
