Data. You bring data to the table and let them make the rational decision. No reason to convince them of anything, let the stats speak for themselves. It's marketing; its point is to drive sales and increase brand exposure right? These days (especially with digital campaigns) these things are measurable. But you also need to be open to the fact that your opinion really doesn't matter. Maybe the ugly banners have higher click-through-rates or lead to a lower cost-per-acquisition than a prettier alternative. If that's the case, pretty doesn't matter. But if your hunch is correct then you should be experiencing substandard click-throughs, higher than normal CPA, etc; and you can point that out to them without being confrontational.
