Is a 10-inch or 12-inch subwoofer better for a car?

Across the car-audio communities we read, the rough consensus is that 10-inch subs tend to be punchier and faster (better for rock, metal, and sealed enclosures), while 12-inch subs move more air and dig lower in frequency, which suits hip-hop and EDM. Cabin size, trunk space, and how the box is tuned matter more than driver diameter alone.
