Design-wise, I chose Miraidon. Miraidon has a much more sleeker design that doesn't look too over-the-top and silly. The other Pokémon, Koraidon, aka the Pokémon that looks like Firestone is his favorite restaurant, looks as if it has trouble deciding whether it wants to be a lizard, bird, a Native American tribal chief, or a motorcycle. The way it looks as if it has a tire stuck in its throat was silly when it was first revealed and even sillier now when you see in action. I understand that it is supposedly based upon a motorcycle, but simply because it's meant to be ridden doesn't mean that it requires such a silly design. We were able to ride Pokémon such as Tauros, Mudsdale, Wyrdeer, etc. and they don't have silly designs. To make matters worse, he also looks even sillier when he's being ridden because, despite looking even more like motorcycle than Miraidon, he doesn't even look like he's using his "wheels." Instead, he runs on his feet like the Flintstones when they're "driving." Surely I can't be the only one that believe that it defeats the purpose of resembling a motorcycle. At least Miraidon moves more like a cooler, futuristic motorcycle. If my theory is correct about their battle styles, I believe Miradion is likely to be Dragon/Electric-type and the special attacker of the duo, while the other is likely to be Dragon/Fighting-type and the physical attacker. If so, I would have to go with choosing Pokémon Violet to get Miraidon because Mr. Throat Tire would only struggle really badly against Fairy-types, which tend to dominate meta games. Maybe the mechanics that allow Pokémon to change type could help Koraidon in that regard. If so, then what I choose would highly depend on the stats, whether or not I need a physical or special attacker, or what type could cover most of the meta game in this generation.
