The information in the ad is biased and self-serving, so right off the bat I ignore almost anything they say.
I dont get that feeling at all when a company boasts about "best x, or won y competition" but bashing another product looks childish, mean and immature. A "my kid is better than yours" kind of debate.
I honestly embarrased for them when I see an ad that portrays competitions as mentally inept or comically retarded.
