Not really. At the end of the day if neither is wanted and neither can be deleted it's pretty much the same thing for the most part irrespective whether they are official or unofficial.
Tim Cook has said the reason Apple's pre installed apps can't currently be deleted is because certain functionality of the OS itself depends on the stock apps. For example, since you can't change default apps, deleting the Mail application then tapping on an email address in another application would cause the universe to implode.
Or something.
