In practice, both of your points can be true. But a good quality 12, 13, 15, 18, or 21" sub will be every bit as tight or "fast" as an equivalent quality 10". There is nothing magical about a 10" subwoofer. Ported boxes don't have to sound boomy. In fact, undersized sealed boxes can also sound very boomy.
I personally think that 12" subs represent the very best bass in the value chain, all things considered.
