It depends too much on the context of the conversation, and what else is said surrounding it.
Of course, for some it doesn't usually matter, like, "I like the Marauder's design", as opposed to something like, "I like the Shadow Hawk's design".
Most people like the Marauder and the effectiveness of its loadout, so it doesn't really matter, however, the Shadow Hawk's technical designs (particularly in Introtech which is where people think of designs first where available), tend to be a poor performer, so usually references its aesthetics.
However, most conversations like this usually have other sentences involved in the conversation, so it's usually pretty easy to tell what a person is usually referring to and provide the context.
