They are definitely by shape (mostly, sweet potato is the odd one out), not seasoning. You can add Cajun seasoning to any of those and they’d still be what shape they are. Just like I prefer curly fries, but I don’t like the ones from Arby’s because of their seasoning.
Where the hell are the Cajun fries?
8, 5, 4, 2, 1, 7, 3, 6
Adding Cajun seasoning to 4, 2, 1, or 7 would raise it above the other 3 and make me unsure about whether to raise it above 5.

And the onion rings.
I challenge you to find me a circular fry made from potato.
