It's irrelevant whether one ad gets a better result than another ad, what matters is does any ad drive traffic at a rate cheap enough to build a sustainable business. The "ugly" ad cost $11 to drive a webpage visit. Is this enough to result in a profitable conversion? I'm guessing almost certainly not.
So what does it matter if the "ugly" ad performs better? All that means is you go bankrupt slower. Is there room to improve the performance of the ugly ad so it wanders into the realm of profitability? I'm guessing there's far less room than for the professional ad and, probably, there doesn't exist a design that will drive profitability with the current offering and more focus should be made in customer development to discover and communicate a clear value prop rather than mess around with ad copy.
