Is the US louder than Canada, or is Buffalo louder than TO?

For a long time I've noticed that the commercials on US TV channels are kind of loud and unsubtle. I just assumed this was a difference between the US and Canada.

But it occurs to me that the difference might not be that they're USian and we're Canadian. It might be because the US channels I watch most often are from Buffalo, and the Canadian channels I watch most are from Toronto. Toronto is the biggest city in Canada, whereas Buffalo is smaller and is more of a local centre. So TO is more likely to be able to attract top advertising dollars and talent to make sleek and clever commercials.

What do you think?
