It is always unethical to compare your company's product with a similar product offered by another company when trying to argue that your own company's product is superior.

It is not always unethical to compare your company's product with a similar product offered by another company, but it can be unethical if the comparison is inaccurate or misleading. Companies engage in competitive analysis and comparison frequently as a part of their marketing strategy. However, the comparison should be fair, factual, and verifiable. Misleading comparisons can be considered false advertising, which is unethical and can also result in legal consequences.
