I'm pretty new to English StackExchange, and English is not my first language, so I'm not even sure what tags to look for. So, I apologize if this has been discussed before.
I'm writing up a blog and somehow I got confused with the proper grammar for a sentence that compares one thing to another thing of a different category. For example, I want to compare Dodge Chargers, the car, with Cheetahs, the animal. Which one is the proper sentence:
Dodge Chargers are equivalent to Cheetahs in the animal kingdom.
Dodge Chargers are equivalent to Cheetahs in automobiles.
Do I use the category from the first or second subject?
