The unicorn tag wiki says that unicorn are way better than ponies.
I think this is heavily opinion based and it is against the rules of the site.
My rank would be:
- Pegasus, that can fly so is way better than
- Unicorn, that has a nice horn so it is slightly better than
Of course, the top would be the winged unicorn, but I don't include it in the rank, since as everybody knows, this one don't actually exists.
Please let me know if you agree with me or have another rank you would like to propose.
