Dogecoin isn't a major alternative. we've already seen a timetravel attack on the coin less than 48 hours ago.
Doge definitely has more than "some support by community" right now. It might (and most likely will) turn out to be useless financially in the long-run though, so I agree it's at least debatable.
I actually wasn't aware of an attack just 48 hours ago, could you provide a source?
Stablecoin is not innovative by any stretch of the word.
Since it's revival,
there's a mixing service under development. That's definitely more than most clones have, which should be at the very least mentioned.

Also, the list is lacking FedoraCoin (DogeCoin clone):
